Doctor Who and the Seven Keys to Doomsday

Plot Summary

“Doctor Who and the Seven Keys to Doomsday” follows the Doctor in a newly regenerated form on a perilous quest to stop the Daleks from gaining ultimate power. The play uniquely begins with the Third Doctor collapsing and regenerating on stage – a sequence achieved by showing Jon Pertwee’s face on screens and then introducing actor Trevor Martin as the new Doctortardis.fandom.com tardis.fandom.com. Two audience members (planted actors) named Jenny and Jimmy rush to his aid during this scene, inadvertently becoming the Doctor’s latest companionstardis.fandom.com. Together, they enter the TARDIS and embark on a mission assigned by the Time Lords.

The TARDIS brings the Doctor, Jenny, and Jimmy to the desolate planet Karn, where a great danger loomswww.pagefillers.com. The Doctor reveals that Karn holds seven crystal keys – mystical elements critical to a super-weapon called the Doomsday Weapon. If the Daleks and their minions find all seven crystals, they would be able to control or destroy all life in the universetardis.fandom.com. The trio soon encounters a host of challenges on Karn. They are caught between suspicious human rebels fighting an unseen enemy and the planet’s native horrors, including hairy, semi-intelligent crab-like creatures known as Clawrantularswww.pagefillers.com. As they venture through caves and corridors, the heroes face a deadly computer system and the decaying consciousness of the last Master of Karn, both of which test their wits and couragewww.pagefillers.com.

Throughout the adventure, the Doctor and companions must locate the seven crystal keys before the Daleks do. Each key brings them closer to foiling the Dalek plot. Classic Doctor Who tropes abound – there are captures and escapes, secret passages, betrayal and redemption, and the rallying of allies (the rebels) against the common foewww.pagefillers.com. Ultimately, the Daleks (led in this story by the Dalek Emperor) attempt to assemble the crystals to power a doomsday weapon that would exterminate all organic life except the Dalekswww.pagefillers.com. In a climactic confrontation, the Doctor manages to outwit the Daleks, preventing them from obtaining all the crystals and activating their genocidal devicetardis.fandom.com. By adventure’s end, the Daleks’ plan is thwarted and peace is restored, with the Doctor ensuring the crystals (the “seven keys”) are kept out of evil hands. The storyline encapsulates a self-contained Doctor Who adventure filled with the spirit of the 1960s/70s era – effectively a fast-paced quest against the Daleks with new companions by the Doctor’s sidewww.pagefillers.com www.pagefillers.com.

Key characters: The play’s central character is the Doctor, portrayed here as an alternate incarnation immediately following the Third Doctor’s tenure. Jenny and Jimmy are the Doctor’s companions for this story – ordinary humans thrust into adventure after responding to the Doctor’s call for help. The primary villains are the Daleks, including a commanding Dalek Emperor, with the Clawrantulars serving as their monstrous servants on Karntardis.fandom.com. Additional characters include Karn’s rebel fighters (such as Jedak, a local ally) and the enigmatic Master of Karn, an ancient figure whose remaining intelligence guards one of the keys. The themes mirror classic Doctor Who motifs: courage and ingenuity in the face of evil, the importance of cooperation with local allies, and the race against time to stop a doomsday threat. Despite being produced on stage, the story was ambitious in scope – featuring multiple locales on Karn, various creatures, and the high stakes of a universe-threatening Dalek scheme.

Production History

“Seven Keys to Doomsday” was produced as a live stage play during the winter of 1974, making it one of the earliest attempts to bring Doctor Who from the television screen to the theater. The play was written by Terrance Dicks, who at the time had just finished his tenure as the TV show’s script editorwww.historyvortex.org. Dicks crafted the story to fit in the continuity gap between the Third and Fourth Doctors’ eras, taking advantage of the brief period when Jon Pertwee had left the role and Tom Baker had yet to appear on TVwww.doctorwhonews.net. In fact, the stage premiere occurred while the world was awaiting Tom Baker’s debut, allowing Dicks to introduce a new Doctor on stage without contradicting known continuitywww.historyvortex.org. (In essence, the play presents an alternative Fourth Doctor, portrayed by Trevor Martin, separate from the television canonwww.doctorwhonews.net.)

The show premiered in London’s West End at the Adelphi Theatre on 16 December 1974tardis.fandom.com www.doctorwhonews.net. It was promoted as a family-friendly Christmas holiday event, capitalizing on the popularity of Doctor Who and the Daleks. The initial run was planned for four weeks at the Adelphi, and indeed it ran through late December 1974 into January 1975www.doctorwhonews.net. The production was directed by Mick Hughes, with stage design by John Napier, and notably had Barry Letts (the producer of the Doctor Who TV series at the time) on board as a BBC adviser and coordinatortardis.fandom.com. This official backing ensured continuity with the television series – for example, BBC provided Jon Pertwee’s portrait for the regeneration scene and allowed use of authentic Dalek designs. Dalek creator Terry Nation’s approval was also obtained to feature the Daleks on stagenzdwfc.tetrap.com, making the play fully licensed and authorized in terms of characters and monsters.

Although the play’s story is grand in scale, the stage production had to creatively realize it. According to production notes, the regeneration was staged with Trevor Martin initially appearing in Pertwee-style costume (complete with a wig) and collapsing, followed by a projected image of Pertwee’s face morphing into Martin’s – at which point Martin would discard the disguise and reveal the new Doctortardis.fandom.com. The TARDIS interior was depicted on stage, and scenes on Karn with Daleks and Clawrantula creatures required elaborate costumes and props. James Acheson, who coordinated the monsters, helped design the creature costumes (Acheson would later become an Oscar-winning costume designer, reflecting the talent involved behind the scenes). The production also employed fight choreographers (for action scenes with Daleks and creatures) and special sound effects to recreate the sci-fi atmosphere livetardis.fandom.com.

After the West End opening, there were plans to take “Seven Keys to Doomsday” on a UK tour in 1975. However, external events negatively impacted the production’s success. In late 1974, London was experiencing an IRA bombing campaign, and the threat of terrorism kept many families away from crowded public venuesthetimescales.com. As a result, attendance at the Adelphi shows suffered. Despite positive audience reactions to the play itself, the low turnout made the costly production financially untenabletardis.fandom.com. The intended national tour was ultimately cancelled, and the show closed earlier than expected, ending its run at a financial losstardis.fandom.com thetimescales.com. In total, the original production gave about four weeks of performances, making it a short-lived but memorable part of Doctor Who history.

Decades later, the legacy of “Seven Keys to Doomsday” saw a brief revival on stage. In 1984, a licensed amateur production was mounted in New Zealand at the Porirua Little Theatre (near Wellington)tardis.fandom.com. This New Zealand production (billed as the first in Australasia) had Terrance Dicks’ blessing and even Terry Nation’s permission for the Daleksnzdwfc.tetrap.com. It premiered on 24 November 1984, coinciding with Doctor Who’s 21st anniversary, and ran for a couple of weeksnzdwfc.tetrap.com. The New Zealand version starred Michael Sagar as the Doctor, who was costumed in a notably different style (a light-checkered suit and sporting a black moustache) to distinguish him from the Trevor Martin interpretationtardis.fandom.com. This international production demonstrated the enduring interest in the play, even though it remained a relatively rare event. Beyond this, “Seven Keys to Doomsday” was not regularly performed again on stage, making these productions unique events in the franchise’s history.

Writer and Origin: It’s worth noting Terrance Dicks originally envisioned using a known Doctor for the stage show. Early in development, he hoped either Jon Pertwee (who had just left TV) or incoming Tom Baker might star in the play, to directly tie it in with the seriestardis.fandom.com. However, neither actor was available for a live theatre commitment. This led to the casting of Trevor Martin, an accomplished actor who had actually appeared on Doctor Who before (he played a Time Lord in the TV serial The War Games in 1969)www.doctorwhonews.net. Martin thus became the first person to play the Doctor on stage. With Dicks’ script and Martin’s performance, the play was able to stand on its own, even without a current TV Doctor in the role. The result was a standalone adventure that bridged the gap on TV (in spirit if not canon) between the Pertwee and Baker eraswww.doctorwhonews.net.

Cast and Crew

Cast (Original 1974 Production): The stage play featured a mix of newcomers and one familiar face from the TV series in the companion role. The Doctor was played by Trevor Martin, portraying a newly-regenerated incarnation of the Time Lordtardis.fandom.com. The Doctor’s companions were Jenny, played by Wendy Padbury, and Jimmy, initially played by James Matthewstardis.fandom.com. (Wendy Padbury was well-known to fans as Zoe from the TV series in the late 1960s, making her casting a special nod; Padbury thus became the first actor to portray two different companions in official Doctor Who productionstardis.fandom.com. James Matthews was a young actor in the role of Jimmy; partway through the run, Simon Jones took over the role of Jimmy as an understudy/replacementtardis.fandom.com guide.doctorwhonews.net.) Other characters on Karn were portrayed by a supporting cast: Jedak, one of the human rebels, was played by Ian Ruskin; Tara (another rebel) was played by Patsy Dermott; Garm was played by Anthony Garner; and Marko (sometimes spelled Marco in sources), another supporting character, was played by Robin Brownetardis.fandom.com guide.doctorwhonews.net. The mysterious Master of Karn – essentially the guardian of Karn’s secrets in the plot – was played by Simon Jones (doing double duty in the production)tardis.fandom.com guide.doctorwhonews.net.

On the villains’ side, the Dalek Emperor was realized on stage and voiced by Jacquie Dubin (one of the few instances of a female performer voicing a Dalek character)tardis.fandom.com guide.doctorwhonews.net. The Dalek drones themselves were operated by actors in costume; Peter Jolley provided the Dalek voices during performances and also physically operated a Dalek prop on stagetardis.fandom.com. The Clawrantulars (the Daleks’ crab-like henchmen) were portrayed by three performers in creature suits: Peter Jolley, Mo Kiki, and Peter Whitting each took on the role of a scuttling Clawrantula when requiredtardis.fandom.com. (Mo Kiki, notably, was not only a performer but also the fight arranger for the show’s action scenes, handling choreography for battles between the Doctor’s side and the monsterstardis.fandom.com.)

Crew and Creative Team: The play was penned by Terrance Dicks (Writer), adapted from his own imagination of a Doctor Who adventure suitable for stagetardis.fandom.com. Direction was by Mick Hughes, who handled the challenge of translating the fast-paced, effects-heavy story to live theatertardis.fandom.com. Set and costume design was led by John Napier (Designer), who had to create everything from the interior of the TARDIS to the alien landscapes of Karn on the Adelphi stagetardis.fandom.com. Sound effects were overseen by Philip Clifford, ensuring the TARDIS dematerialization, Dalek voices, and other sci-fi sounds came across to the audiencetardis.fandom.com. The production’s supervisor was Trevor Mitchell, and the BBC assigned Barry Letts as a production coordinator to liaise with the theatre companytardis.fandom.com. Barry Letts’ involvement lent authenticity and continuity – he was instrumental in supplying the necessary Doctor Who elements (for example, arranging use of the TARDIS prop image and Pertwee’s likeness). As mentioned, Mo Kiki served as fight arranger, coordinating any physical altercations on stagetardis.fandom.com. James Acheson handled monster coordination, effectively in charge of costumes/props for the Daleks and Clawrantulastardis.fandom.com. (Acheson’s creative designs for the creatures were noteworthy – he would later achieve fame as a costume designer for films.) The collaborative effort of this cast and crew resulted in a distinctive theatrical experience that brought Doctor Who’s adventure to life on stagetardis.fandom.com tardis.fandom.com.

Reception

Contemporary Reaction (1974–75): Upon its debut, Seven Keys to Doomsday was met with a generally positive reception from those who saw it. Contemporary press and audience reports indicated that it was an entertaining slice of Doctor Who in a new medium. The play’s story, with its mix of familiar Doctor Who elements (Daleks, a planet in peril, a fast-paced quest), was engaging for fans. A later retrospective noted that “1974’s Seven Keys To Doomsday* presented an entertaining story”* on stagewww.denofgeek.com. Critics acknowledged that it captured the spirit of the TV series, even though none of the then-current TV cast were involved (Trevor Martin was a new Doctor and the TV series’ new Doctor, Tom Baker, did not participate in the production)www.denofgeek.com. For children in the audience especially, seeing the Daleks and the TARDIS live was a thrill. The play’s action, monsters, and humor were crafted to appeal to a family audience, and this was largely successful – one fan who later reviewed the story remarked that it “is just an exciting and wonderfully traditional Who story…kid-friendly…it truly entertains”www.pagefillers.com.

It’s important to note that the show’s financial performance did not reflect any lack of quality or enjoyment, but rather external circumstances. As mentioned, fears of bomb threats in London meant many potential theatergoers stayed homethetimescales.com. This depressed ticket sales and prevented the play from reaching a wide audience. Those who did attend generally had positive impressions – the adventure was described as very faithful to the tone of the TV series and fun for fans. In fact, in later analysis, it’s said “the play was very well received” by audiences and critics on its own meritsthetimescales.com. Unfortunately, the limited run and early closure meant contemporary reviews were not as widespread as they might have been for a longer-running show. However, Doctor Who Magazine and other fan outlets at the time reported favorably on the production, and the novelty of a Doctor Who stage play was noted with enthusiasm.

Retrospective Reviews: In the years and decades after 1974, Seven Keys to Doomsday gained a bit of a cult reputation among Doctor Who fans. For a long time, only those who had attended the play or read summaries knew its story, but it was often talked about in Doctor Who circles as a “lost” adventure. When the script was later adapted into an audio drama (see below), a wider array of fans experienced the story and reviewed it. Many found it to be a quintessential “Classic Who” adventure, in both positive and negative senses. Some reviewers point out that the plot is jam-packed with classic Doctor Who tropes – from running down corridors to puzzle-solving and Dalek scheming – to the point of being “full of clichés”. But this was not seen as a flaw by others; instead, it felt like a loving homage. As one critic put it, “The Seven Keys to Doomsday is nothing but clichés…But they are Doctor Who clichés… the perfect distillation of the Doctor Who formula – at least of the Classic Series”www.pagefillers.com. This reviewer (E. John Winner) actually praised the play highly, calling it one of his favorite Doctor Who stories and celebrating it for capturing the essence of the late 1960s/early 1970s erawww.pagefillers.com.

The dialogue and characters also received praise for matching the tone of the TV series. Trevor Martin’s performance as the Doctor was often lauded in hindsight; even without being a TV Doctor, he conveyed the Doctor’s wit and authority well. One retrospective reviewer noted that Martin was “very good as the Doctor” and that the companions Jenny and Jimmy served their purpose admiringly in the adventurewww.amazon.com www.pagefillers.com. Fans also enjoyed Wendy Padbury’s presence, with some regret that her character Jenny exists only in this story. The stage limitations (such as fewer locations and simpler effects) meant the story was straightforward and fast-moving, which retrospectively has been seen as a strength – it doesn’t “waste time” and keeps the audience entertainedwww.pagefillers.com.

That said, some critiques have been offered. A few fans feel the play’s original format made it somewhat simplistic, aiming at a pantomime-like family audience with very broad strokes. The invented monsters like the Clawrantulars have been met with a bit of bemusement – even Terrance Dicks joked later that the name “Clawrantula” was clearly devised to delight children, not to impress serious adultswww.pagefillers.com. In sum, Seven Keys to Doomsday is remembered fondly. Contemporary reviewers found it fun and faithful, and later audiences (via audio adaptations or written accounts) generally agree that it’s a solid, if conventional, Doctor Who adventure. Its novelty value as a stage play and the enthusiasm of the cast and crew have given it a positive reputation over time. Despite the troubled timing of its original run, Seven Keys to Doomsday is often regarded as a successful experiment in translating Doctor Who to the stage – enjoyable for those lucky enough to witness it and still intriguing to fans exploring Doctor Who’s more unusual outingswww.denofgeek.com thetimescales.com.

Legacy and Influence

Though Doctor Who and the Seven Keys to Doomsday exists outside of the main televised canon, it holds an important place in the Doctor Who franchise history. It was the first time the Doctor was portrayed in an original story on stage, effectively creating an “alternative Doctor” for the theater. Trevor Martin’s Doctor is sometimes fondly referred to as a “Stage Doctor” by fans, analogous to how Peter Cushing is an alternate film Doctor from the 1960s. This pioneering stage venture demonstrated that Doctor Who could extend into other media and paved the way for later productions. In 1989, another stage play The Ultimate Adventure (also written by Terrance Dicks) would follow, this time even starring two former TV Doctors (Jon Pertwee and Colin Baker on different nights). Seven Keys set the template that live Doctor Who could work, mixing familiar elements with new characters in a self-contained story.The play’s content itself influenced subsequent Doctor Who lore in subtle ways. Notably, the planet Karn – the primary setting of Seven Keys to Doomsday – was an invention of Terrance Dicks for this stage story. Dicks later reused the planet Karn in the television script “The Brain of Morbius” (1976), which he co-wrote for the Fourth Doctor’s TV seriestardis.fandom.com. In that TV serial, Karn is home to the Sisterhood of Karn and a notorious Time Lord criminal, concepts that were new to viewers but the name had its origin in the stage play. This is a direct legacy: an element from an “unseen” Doctor Who story migrated into official canon on screen. Additionally, some plot ideas in Seven Keys anticipated later developments in the franchise. The premise of the Doctor and companions searching for a set of powerful crystals to avert universal catastrophe can be seen as a precursor to the Key to Time saga in Season 16 of the TV series (1978). In the Key to Time arc, the Fourth Doctor and Romana collect six segments of a cosmic key – a similar treasure hunt structure. Critics have noted that Seven Keys to Doomsday’s “basic plot device – the search for the crystal of power – eventually regenerates into the Key to Time sequence” a few years laterwww.pagefillers.com. It’s quite likely that Terrance Dicks’ experience with the stage play’s plot informed or inspired the later use of a segmented quest in the series.

Several other parallels have been drawn. The play features the Dalek Emperor and a Doomsday Weapon – concepts that echo earlier Dalek stories (the Dalek Emperor had appeared in 1967’s Evil of the Daleks on TV, and a “doomsday” device was central to the 1970 TV story The Daleks’ Master Plan). By bringing these ideas to the stage, the play reinforced their iconic status. When the new series of Doctor Who (2005 onwards) eventually featured the Dalek Emperor and planet-wide Dalek plots, it was treading ground familiar to long-time fans from both classic episodes and this stage adventure. Seven Keys also had a “Master of Karn” as a villain (not to be confused with “the Master” character from TV). This notion of a disembodied or ancient intellect guiding a super-weapon on Karn bears resemblance to Morbius in The Brain of Morbius (an ancient brain controlling things on Karn)www.historyvortex.org. Essentially, Terrance Dicks carried over motifs from the play into televised Doctor Who – Karn, disembodied evil intelligence, and even the general atmosphere of a Gothic quest – thereby influencing the tone of mid-1970s Doctor Who.

Within the franchise’s expanded universe, Seven Keys to Doomsday holds a niche but memorable spot. It is frequently mentioned in reference guides and fandom retrospectives about “alternate Doctors” or spin-off media. For instance, the TARDIS Eruditorum and other fan analyses often list Trevor Martin’s Doctor alongside other non-canonical Doctors, acknowledging him as part of the wider mythos. The play is also cited as an example of Doctor Who’s flexibility – in the 2010s, articles reflecting on Doctor Who stage shows described Seven Keys as a bold early venture (albeit one launched under challenging conditions)www.denofgeek.com. Modern Doctor Who Live arena shows and immersive theatre experiences can trace a lineage back to what Seven Keys to Doomsday attempted in 1974.

Moreover, the story’s revival in audio form (discussed below) introduced it to new audiences, effectively canonizing it in the audio medium. Big Finish Productions, which creates licensed Doctor Who audio dramas, included Seven Keys to Doomsday in their Stageplays series, treating it with the same respect as a “Lost Story.” This has helped cement the play’s legacy as an officially recognized adventure within the Doctor Who expanded universe. Fans now debate where this alternate Doctor might fit in hypothetical timelines, and the character of Jenny (unique to this story) is sometimes brought up in discussions about companions that “might have been.” Wendy Padbury’s dual roles also set a precedent (years later, actresses like Freema Agyeman and Karen Gillan appeared in Doctor Who as one character and later came back as a main character – somewhat echoing Padbury’s situation of playing two roles in the franchise, albeit Padbury’s was across different media).In summary, while Seven Keys to Doomsday might have been a footnote in 1970s Doctor Who, its influence is seen in later stories (through reused ideas like Karn and crystal quests)www.historyvortex.org www.pagefillers.com, and it remains a beloved oddity in the Whoniverse. It demonstrated the potential for Doctor Who to expand beyond TV and contributed to the rich tapestry of Doctor Who lore that fans continue to celebrate.

Recordings and Adaptations

Given that Seven Keys to Doomsday was a live stage show in 1974, no official video recording of the performance was made (televised theatre broadcasts were not common for such productions, and if any archival filming was done it has never been released). For many years, the primary way to experience the story after the fact was through the published script or synopses in fan magazines. However, in the 2000s, the story found new life through audio adaptation.Big Finish Audio (2008): The most significant adaptation is the audio drama version produced by Big Finish Productions, released in 2008. Big Finish, known for creating audio plays based on Doctor Who, launched a special “Doctor Who Stageplays” series, and Seven Keys to Doomsday was included as installment number 2 in that rangewww.bigfinish.com www.bigfinish.com. The audio adaptation was scripted by Terrance Dicks himself, adapting his 1974 stage script for the audio formatwww.bigfinish.com. This allowed the original author to refine the story slightly and ensure it worked without visuals. The biggest coup of this adaptation was the return of Trevor Martin to the role of the Doctor – over three decades after he first played the part on stagewww.bigfinish.com www.bigfinish.com. Martin, in his 70s, reprised his Doctor for audio, giving fans a chance to hear the “Stage Doctor” in action.

The companions were recast for the audio. Rather than bring back Wendy Padbury as Jenny (Padbury by then was older than the character, who is meant to be a young woman), Big Finish made a clever casting choice: Charlie Hayes was cast as Jenny on audiowww.amazon.com. Charlie Hayes is actually Wendy Padbury’s daughter in real life, which provided a lovely connection to the original productionwww.amazon.com. According to the director John Ainsworth, Padbury’s daughter was “the right age for the part” and it gave “a nice connection to the original production as well”www.bigfinish.com. This bit of behind-the-scenes trivia delighted fans, and Trevor Martin himself was reportedly thrilled with the casting once he learned of the family relationwww.bigfinish.com. The character Jimmy was voiced by actor Joe Thompson in the audio version (since the original Jimmy actors, James Matthews and Simon Jones, were not involved in the adaptation). The Dalek voices on audio were provided by Nicholas Briggs – the same voice actor who voices Daleks in the modern TV series – adding a layer of authenticity and menace to the Dalek dialogue. Big Finish’s production included sound design and music to enhance the atmosphere, from TARDIS sounds to battle scenes, effectively translating the action that would have been seen on stage into an immersive audio experiencewww.pagefillers.com.

The 2008 audio drama runs approximately the length of a typical Doctor Who serial (around 60–70 minutes) and was released on CD and download. It has since become the most accessible form of the story. Reviews of the audio were positive, noting that the play’s narrative holds up well. Listeners enjoyed Trevor Martin’s performance and the way the audio managed to convey the epic quest across Karn. Terrance Dicks, present at the recording, approved of the final product – he found it fascinating to realize his stage play in a purely audio medium and was pleased with the resultwww.bigfinish.com. This adaptation has essentially preserved Seven Keys to Doomsday for posterity, allowing new generations of fans to experience this once-elusive Doctor Who adventure in full.

Script and Novelization: There has never been an official Target novelization or book release of Seven Keys to Doomsday. Unlike some other stage plays (The Ultimate Adventure was novelized by Terrance Dicks in 1989), Seven Keys remained only in script form. The original script is archived, and over the years, fan clubs had access to it. For example, the New Zealand production in 1984 used Terrance Dicks’ script with his permissionnzdwfc.tetrap.com. Excerpts and detailed summaries have appeared in fan publications (the Time-Space Visualiser fanzine produced an article discussing the play and its NZ stagingnzdwfc.tetrap.com). It wasn’t until the Big Finish audio that a full commercial script adaptation was available to the public. In essence, the 2008 audio now serves the role a novelization would – it’s a faithful telling of the story that fans can easily obtain.

No known audio recordings of the 1974 live performances have surfaced. It’s possible that an unofficial audio tape was made by an audience member (as sometimes happened with old stage shows), but if so, it remains private. Thus, the Big Finish production is the definitive recording. Additionally, in 2017, a short documentary “Remembering Seven Keys to Doomsday” was produced (included on a special release or online) which features interviews with Terrance Dicks and others reminiscing about the playtardis.fandom.com. There have also been interviews like Toby Hadoke’s Who’s Round podcast episodes 200 and 201, which included conversations with people involved in the stage playtardis.fandom.com. These provide behind-the-scenes insight but are not dramatizations of the story itself.

In summary, while the original 1974 performance can no longer be witnessed, Doctor Who and the Seven Keys to Doomsday lives on through its audio adaptation and the preservation of its script. The audio drama, with Trevor Martin starring once more, is a cherished adaptation that keeps this adventure as part of the wider Doctor Who experience. Fans can also find the script details and analysis in various Doctor Who reference books and websites, ensuring that the story continues to be documented and appreciated.

Additional Trivia and Rare Information

Title Variations: The play’s title is sometimes given with slight differences. Promotional posters in 1974 called it “Doctor Who and the Daleks: Seven Keys to Doomsday,” whereas the theatre programme included the word “in” (i.e. “Doctor Who and the Daleks in Seven Keys to Doomsday”)tardis.fandom.com. This has led to minor confusion, but both refer to the same production.
Regeneration on Stage: The opening regeneration scene was a clever technical trick for live theatre. Trevor Martin began the show dressed as the Third Doctor – complete with Jon Pertwee-style velvet jacket, ruffled shirt, and even a wig to resemble Pertwee’s hairtardis.fandom.com. When “injured,” he collapsed and the regeneration was shown by projecting images of Pertwee’s face that slowly morphed into Martin’s face on screentardis.fandom.com. Martin then removed the wig and costume’s Pertwee-style collar to indicate he had transformed into a new Doctortardis.fandom.com. This made Trevor Martin the first actor to portray two incarnations of the Doctor in one production (Third and Fourth), predating the similar trick on TV in 1987 when Sylvester McCoy briefly wore Colin Baker’s wig to regenerate as the Seventh Doctortardis.fandom.com.
Wendy Padbury’s Unique Role: Having Wendy Padbury (formerly companion Zoe) play Jenny gave the play a bit of Doctor Who pedigree on stage. This casting made Padbury the first performer to play two distinct companions in Doctor Who lore (one on TV, one on stage)tardis.fandom.com. It’s a rarity for an actor to portray two different companions; Padbury’s participation likely drew some fans of the Troughton era to see the show. (Incidentally, Padbury’s future daughter Charlie Hayes would portray Jenny in the audio adaptation decades later, as noted above.)
Behind-the-Scenes Challenges: Trevor Martin took his role so seriously that he altered his appearance for the part, growing his hair longer to fit the Doctor’s eccentric look. Offstage, however, this led to unexpected trouble – Martin reported being harassed on the London Underground by youths who made fun of his long hair, to the point where he described the look as giving him an “effeminate” appearance that invited unwanted attentiontardis.fandom.com. Despite these incidents, Martin continued with the chosen hairstyle throughout the run.
Connections to the TV Series: Barry Letts’ involvement as a BBC coordinator meant that elements like the TARDIS prop and Dalek props were of high quality. The Daleks on stage were said to be virtually indistinguishable from their TV counterparts of that era, and their famous stilted voices were recreated live (with Peter Jolley internally modulating his voice). Terry Nation’s agreement for the Daleks is noteworthy – at the time, Nation owned rights to the Daleks and had to individually approve their use outside the TV shownzdwfc.tetrap.com. His green-light shows the production was considered an official extension of Doctor Who, not a fan production.
Second Ever Dalek Stage Play: This was actually the second time Daleks appeared on the theatrical stage. The first was a 1965 play called “The Curse of the Daleks,” which oddly did not feature the Doctor at all (it was a Terry Nation-penned standalone sci-fi play). Seven Keys to Doomsday therefore was the first stage play to feature the Doctor himself. It set a precedent that any future stage shows should include the Doctor as the hero.
Alternate Doctor Acknowledgement: Fans often wonder where Trevor Martin’s Doctor might fit in the continuity. While it’s not canon in the TV series, the play explicitly presents him as the Fourth Doctor (since it occurs right after Pertwee’s Third). Of course, on TV the Fourth Doctor is Tom Baker, so the stage Doctor is an alternate timeline. Some enthusiastic fans like to imagine that perhaps this story takes place in a parallel universe. The Big Finish audio adaptation embraced the story without firmly placing it in continuity, essentially treating it as a standalone “What if?” scenario.
Influence on Later Media: Terrance Dicks recycled and re-imagined elements of this play in later stories. Aside from Karn and the quest concept, the idea of the Doctor working with two new young companions (neither of whom is from his usual TV roster) can be seen echoed in the 1990s Doctor Who novels (often the Doctor would have novel-exclusive companions for new adventures). It’s a testament to Dicks’ creativity that Jenny and Jimmy feel like authentic Who companions despite only existing in this story. In fact, some fan-written short stories and audio dramas have even referenced Jenny and Jimmy in passing, as a nod to the play’s events.
Porirua Production Anecdote: The 1984 New Zealand production had its own quirks. With Michael Sagar’s Doctor sporting a moustache and different outfit, that version of the Doctor visually evoked a completely separate persona. Brian Hudson, the director of the NZ play, obtained BBC authorization and even local TV coverage. It shows that Seven Keys to Doomsday had appeal far beyond its London origins – reaching fans on the other side of the world who were eager enough to build their own Dalek props and stage the adventure two decades laternzdwfc.tetrap.comnzdwfc.tetrap.com.
Merchandise and Collectibles: Because the play had a short run, there wasn’t much merchandise. However, the Adelphi Theatre did produce a programme booklet and there were promotional flyers/posters. These items are now quite rare. Surviving copies occasionally appear in auctions or collections, often valued by fans as unusual Doctor Who collectibles. Photographs from the production (such as Trevor Martin in costume alongside Daleks) have been published in magazines and books about Doctor Who’s history.
