List of references to other DWU media in live-action and animated BBC stories

Abslom Daak, a recurring character from the Doctor Who DWM comic stories, had a cameo in TV: Time Heist.

References to non-televised works in live-action BBC DWU stories can be few and far between, but over the years, writers have slipped in references to characters, places, and events which originated in media other than the parent show.

Although starting as early as the show's second season, with Terry Nation striving to maintain continuity between televised Dalek material and the Skarosian tyrants' solo appearances in printed media, this behaviour became more common with the advent of the 2005 series of the show, with writers having lived through, and even participated in the writing of, the novels, comics, and audio stories of the 80s, 90s, and early 2000s.

Doctor Who

Classic era

Season 2

• The Dalek Invasion of Earth ^[+]Loading...["The Dalek Invasion of Earth (TV story)"] used the term "Dalekanium" to refer to the metal that comprises the casing of a Dalek. The term, spelled "Dalekenium", had first been used several months earlier in the comic The Humanoids ^[+]Loading...["The Humanoids (comic story)"] in The Dalek Book. It would remain a frequently used term, both on television and in other media, through to the 21st century.

Season 4

• David Whitaker's The Power of the Daleks ^[+]Loading...["The Power of the Daleks (TV story)"] was set on the planet Vulcan, which first appeared two years earlier on a star chart in the comic Invasion of the Daleks ^[+]Loading...["Invasion of the Daleks (comic story)"]. The comic was co-written by Whitaker and fellow television writer and Dalek creator Terry Nation.
• The Evil of the Daleks ^[+]Loading...["The Evil of the Daleks (TV story)"]:
  • This story marks the first televised appearance of the Dalek Emperor, not counting their brief appearance in The Man from MI.5 ^[+]Loading...["The Man from MI.5 (TV story)"]. The Dalek Emperor also first appeared in Invasion of the Daleks. It was implied at the time that the two Emperors were the same individual, and later works would confirm this by identifying them as the Dalek Prime.
  • Although in his early appearances the Dalek Emperor operated a small and mobile casing, he had been shown to transition to a huge, static casing located in the Great Hall of the Dalek City for the sake of increased intelligence the year prior in The Secret of the Emperor ^[+]Loading...["The Secret of the Emperor (comic story)"], a story printed in The Dalek Outer Space Book.

Season 6

• The War Games ^[+]Loading...["The War Games (TV story)"] introduces the Time Lords, a highly advanced civilisation who were the inventors of the TARDIS. The notion that the Doctor's TARDIS had been built by a highly advanced civilisation had earlier been spoken of by the First Doctor in the Doctor Who Annual 1966 short story Peril in Mechanistria ^[+]Loading...["Peril in Mechanistria (short story)"].

Season 9

• In The Sea Devils ^[+]Loading...["The Sea Devils (TV story)"], the Third Doctor says that Horatio Nelson was a friend of his. The Second Doctor had met Nelson in the Doctor Who Annual 1968 short story H.M.S. Tardis ^[+]Loading...["H.M.S. Tardis (short story)"].

Season 10

• Frontier in Space ^[+]Loading...["Frontier in Space (TV story)"] featured a future Earth being ruled by a President of Earth. The title had first appeared in the DWU in a TV Century 21 short story, Battle in Space ^[+]Loading...["Battle in Space (short story)"].
• The Dalek Supreme in Planet of the Daleks ^[+]Loading...["Planet of the Daleks (TV story)"] shares its black and gold colour scheme with the Dalek Leader from the comic strip *Sub Zero ^[+]Loading...["*Sub Zero (comic story)"], which predated the serial by a year.

Season 11

• Planet of the Spiders ^[+]Loading...["Planet of the Spiders (TV story)"] used Brigadier Alistair Gordon Lethbridge-Stewart's forename for the first time on TV. The name was previously given in non-fictional elements of The Making of Doctor Who, using the alternate spelling of "Alastair", with the in-universe recap The Trial of Doctor Who, in the same publication, giving his first initial as "A.".

Season 12

• In Robot ^[+]Loading...["Robot (TV story)"], Sarah Jane Smith berates Benton after he chases off K1, prompting him to reply: "The US Cavalry never got treated like this." Sarah previously called for the US Cavalry to fend off the Daleks during the audio segments meant for the live performance at Goodwood Motor Circuit on 18 May 1974. Robot began airing in December of that year. (In the novelisation, the line is less specific: "The US Cavalry never get treated like this.")
• Genesis of the Daleks ^[+]Loading...["Genesis of the Daleks (TV story)"]:
  • The Fourth Doctor's recollection of the conclusion of the Dalek invasion of Earth fails to tally with the on-screen events of The Dalek Invasion of Earth ^[+]Loading...["The Dalek Invasion of Earth (TV story)"], but references accounts of the invasion given in spin-off media:
    • Instead of a mere bomb collapsing their tunnelwork, he claims that the Daleks were defeated in part by the power of Earth's magnetic core, something shown in the theatrical film Daleks' Invasion Earth 2150 A.D. ^[+]Loading...["Daleks' Invasion Earth 2150 A.D. (theatrical film)"];
    • Instead of the mid-22nd century, the Doctor tells Davros that the invasion happened in 2000. The 1966 Target novelisation Doctor Who and the Crusaders ^[+]Loading...["Doctor Who and the Crusaders (novelisation)"] mentioned the Dalek invasion as having happened in "the 21st century".
  • Additionally, while it conflicts with its event, the story does borrow some elements from the previous account of the creation of the Daleks given in the first The Daleks comic story, Genesis of Evil ^[+]Loading...["Genesis of Evil (comic story)"]. Beyond the similarity of title, details present in both Geneses but not previously mentioned in (or even conflicting with) the account of the Daleks' origin in The Daleks ^[+]Loading...["The Daleks (TV story)"] include:
    • The Daleks' casings having been invented by one of the Daleks' humanoid ancestors before the actual Dalek mutants (instead of the Daleks having built them themselves after mutating).
    • The Daleks' ancestors having already been the aggressors in the war against the Thals, rather than initially innocent victims of warmongering, slave-driving Thals as suggested in the original Dalek story.
    • The Daleks' ancestor taking refuge in a bunker, and becoming one of the last survivors of the original Dalek race.
    • The Daleks vowing to conquer the rest of the universe almost immediately after being created and supplanting their makers.
  • Although interpreted by later lore as a once-normal-looking man who was disfigured in an explosion, Davros seems originally to have been intended to be a mutant himself; indeed, he would be identified as such by the Movellans in Destiny of the Daleks ^[+]Loading...["Destiny of the Daleks (TV story)"]. His appearance recalls the humanoid Daleks of Genesis of Evil, with an enlarged, wrinkled forehead. The History of the Daleks would later point to the comics' humanoids as later descendants of the Kaleds at a later stage of mutation.
  • Davros creates the Dalek mutants by "accelerating the evolution" of the Kaleds. In a different pre-1975 account of the Daleks' origin, We are the Daleks! ^[+]Loading...["We are the Daleks! (short story)"], also written by Terry Nation, he had already presented the Dalek mutants as the result of artificially accelerated evolution, that time of transplanted humans at the hands of the Halldons.

Season 13

• The Brain of Morbius ^[+]Loading...["The Brain of Morbius (TV story)"] is set on Karn, which was first a setting in the stage play Doctor Who and the Daleks in Seven Keys to Doomsday.

Season 17

• Destiny of the Daleks ^[+]Loading...["Destiny of the Daleks (TV story)"]:
  • This story features a Dalek lie detector, which first appeared in the comic story City of the Daleks ^[+]Loading...["City of the Daleks (comic story)"].
  • The Doctor uses his hat to block a Dalek's eyestalk, just as he did in the comic story The Trodos Ambush ^[+]Loading...["The Trodos Ambush (comic story)"].

Season 19

• In Castrovalva ^[+]Loading...["Castrovalva (TV story)"], the Doctor levitates himself, which he learned to do in a TV Comic story.

Season 22

• In Revelation of the Daleks ^[+]Loading...["Revelation of the Daleks (TV story)"], a Glass Dalek makes an appearance. A Dalek with glass casing first appeared in Doctor Who in an Exciting Adventure with the Daleks ^[+]Loading...["Doctor Who in an Exciting Adventure with the Daleks (novelisation)"].

Season 25

• In Remembrance of the Daleks ^[+]Loading...["Remembrance of the Daleks (TV story)"], the casing used by Davros as Dalek Emperor has a spherical upper section, thus having a similar silhouette to the casing used by the original Dalek Emperor in the TV Century 21 Daleks comics. Indeed, at an early stage in planning of the storyline, Remembrance was planned to feature the Emperor in earnest.

30th Anniversary Special

• Dimensions in Time ^[+]Loading...["Dimensions in Time (TV story)"] features a brief cameo by Zog from the stage play The Ultimate Adventure.

BBC Wales era

The Number 22 to Putney Common appears in Rose.

• Rose ^[+]Loading...["Rose (TV story)"]:
  • A London double decker bus resembling Iris Wildthyme's Celestial Omnibus, the Number 22 to Putney Common, can be glimpsed in the opening scenes.
  • The concept of a time war originated in the Doctor Who Magazine comic 4-D War ^[+]Loading...["4-D War (comic story)"], where Time Lords of the Dark Times fight in the Black Sun War. The concept would later become a major part of the War in Heaven of the BBC Eighth Doctor Adventures, before eventually finding its way onto television in the form of the Last Great Time War, initially mentioned in Rose ^[+]Loading...["Rose (TV story)"].

• In The Parting of the Ways ^[+]Loading...["The Parting of the Ways (TV story)"], the Doctor claims that ancient Dalek legends refer to him as the "Oncoming Storm", a title that was first applied to him in the novels Love and War ^[+]Loading...["Love and War (novel)"] and Vampire Science ^[+]Loading...["Vampire Science (novel)"]. It would remain frequently used in subsequent years of televised and non-televised media alike.

  • K9 Mark IV makes his debut at the end of the story. His existence was first revealed by the Eighth Doctor in the novel Interference - Book Two ^[+]Loading...["Interference - Book Two (novel)"].
• In The Girl in the Fireplace ^[+]Loading...["The Girl in the Fireplace (TV story)"], young Reinette asks what monsters have nightmares about and the Doctor responds, "Me." A similar exchange took place in the novel Love and War ^[+]Loading...["Love and War (novel)"].

• The Satan Pit ^[+]Loading...["The Satan Pit (TV story)"] mentions the existence of a Kaled God of War.

• Love & Monsters ^[+]Loading...["Love & Monsters (TV story)"] contained several adverts and posters for Millingdale ice cream. Millingdale ice cream was a fictitious brand of ice cream created for an in-universe website to coincide with the first few series of the 2005 revival of the series.
• Army of Ghosts ^[+]Loading...["Army of Ghosts (TV story)"] hinges on the existence of "the Void", being the space between universes. Although the "dimensional divide" was first referenced on television in Inferno ^[+]Loading...["Inferno (TV story)"], it was the DWM comic story Voyager ^[+]Loading...["Voyager (comic story)"] which first described what lay beyond the Doctor's universe with the name of "the Void" — and, incidentally, the first story to attempt to depict it visually.
• Doomsday ^[+]Loading...["Doomsday (TV story)"] includes the first televised reference to rels, a Dalek measurement of time. A Dalek unit called a "rel" was created in 1964's The Dalek Dictionary, where it measured "hydro-electricity"; it was first depicted as a unit of time in the film Daleks' Invasion Earth 2150 A.D. ^[+]Loading...["Daleks' Invasion Earth 2150 A.D. (theatrical film)"], and had since appeared in comics and audios.

• The Stolen Earth ^[+]Loading...["The Stolen Earth (TV story)"]:
  • Although the final design of the Supreme Dalek only retains the three dome lights (in place of the typical two) as evidence of it, concept art proves that its design was influenced by the TV Century 21 Golden Emperor's, much like that of Davros's imperial casing in Remembrance of the Daleks ^[+]Loading...["Remembrance of the Daleks (TV story)"].
  • Davros has a mechanical hand that replaced the one shot off in Revelation of the Daleks ^[+]Loading...["Revelation of the Daleks (TV story)"]. He was first depicted this way in the audio play The Juggernauts ^[+]Loading...["The Juggernauts (audio story)"].

  • In a flashback to the creation of the Eye of Harmony in the novel Interference - Book One ^[+]Loading...["Interference - Book One (novel)"], the words Rassilon pronounced just before switching on the machinery, creating conventional time, were "For our children.

In fact, I believe he is the most complex space-time event there has ever been anywhere". Elements from Continuity Errors would be echoed more indirectly in other TV stories by Moffat, both earlier (as with the giant library setting of Silence in the Library ^[+]Loading...["Silence in the Library (TV story)"]) and later (as with A Christmas Carol ^[+]Loading...["A Christmas Carol (TV story)"], which would revisit the premise of the Doctor using time travel to intervene in a character's life to slightly alter their outlook on a situation in the present).
• Vincent and the Doctor ^[+]Loading...["Vincent and the Doctor (TV story)"]

• The colony planet in Smile ^[+]Loading...["Smile (TV story)"], though not named in dialogue, was identified in advertising and reference material around the time of the episode's release as Gliese 581d, a link eventually confirmed in a narrative work in the 2018 Doctor Who Annual. This planet had first been mentioned as a future human colony ten years earlier in All Snug in Their Beds ^[+]Loading...["All Snug in Their Beds (short story)"], a Fourth Doctor short story printed in Short Trips: The Ghosts of Christmas.
• In Thin Ice ^[+]Loading...["Thin Ice (TV story)"], the Twelfth Doctor says he has been to the Frost fair a few times before.

• In World Enough and Time ^[+]Loading...["World Enough and Time (TV story)"], Nardole asks the Doctor how he manages to use Venusian aikido, given that the martial art required five arms. While Venusian aikido was first used in the TV story Inferno ^[+]Loading...["Inferno (TV story)"], it was the 1994 Virgin Missing Adventures novel Venusian Lullaby ^[+]Loading...["Venusian Lullaby (novel)"] which first featured five-armed Venusians, with the Virgin New Adventures novel First Frontier ^[+]Loading...["First Frontier (novel)"] making the connection between the art and the five-armed species a month before.
• When recalling the planets on which the Cybermen have originated in The Doctor Falls ^[+]Loading...["The Doctor Falls (TV story)"], the Twelfth Doctor mentions Marinus, which had been revealed as a Cyberman origin planet in the Doctor Who Magazine comic The World Shapers ^[+]Loading...["The World Shapers (comic story)"]. However, it also conflicts with that comic in that it mentions Marinus, Mondas, and Planet 14 as separate planets.
• Twice Upon a Time ^[+]Loading...["Twice Upon a Time (TV story)"]:
  • When the First and Twelfth Doctors meet, time freezes. The same thing happened when the First and Eighth Doctors met in the novel The Eight Doctors ^[+]Loading...["The Eight Doctors (novel)"].

• In The Battle of Ranskoor Av Kolos ^[+]Loading...["The Battle of Ranskoor Av Kolos (TV story)"], the Doctor summons the TARDIS with the sonic screwdriver, which the War Doctor first did in the audio The Thousand Worlds ^[+]Loading...["The Thousand Worlds (audio story)"].
• Resolution ^[+]Loading...["Resolution (TV story)"]:
  • The reconnaissance scout variant of Dalek was introduced. A similar concept — a hitherto unseen type of Dalek specialised to "spy out the land for an imminent full-scale invasion", which also arrived on Earth — was seen in the 1966 short story Have Daleks Invaded Scotland? ^[+]Loading...["Have Daleks Invaded Scotland? (short story)"]. Dalek reconnaissance missions were also cited in the Dalek Survival Guide.
  • Dalek laughter is shown to be off-putting to humans, just as it was in the comic City of the Daleks ^[+]Loading...["City of the Daleks (comic story)"].

Series 12

• Spyfall ^[+]Loading...["Spyfall (TV story)"]:
  • It is mentioned that Graham O'Brien hailed from Essex. This hometown was first mentioned in Graham's character profile on the official Doctor Who website and hinted at in the novel The Good Doctor ^[+]Loading...["The Good Doctor (novel)"].
  • The Doctor makes repairs to the TARDIS that drain the rainforest floor. The TARDIS had been shown to contain a rainforest in the audio story No Place Like Home ^[+]Loading...["No Place Like Home (audio story)"].
• In Fugitive of the Judoon ^[+]Loading...["Fugitive of the Judoon (TV story)"], Ruth Clayton calls the leader of the Judoon "Daddy Rhinoform". The Sixth Doctor referred to the Judoon as "rhinoform bipeds" in the audio drama Judoon in Chains ^[+]Loading...["Judoon in Chains (audio story)"].
• In Praxeus ^[+]Loading...["Praxeus (TV story)"], the Doctor mentions a "talking cat in Ontario". Talking cats, Gallifreyan in origin, were first mentioned in The Legacy of Gallifrey ^[+]Loading...["The Legacy of Gallifrey (short story)"]. The BBC America website corroborated the connection.
• In Can You Hear Me? ^[+]Loading...["Can You Hear Me? (TV story)"], the Doctor mentions that the TARDIS has a jacuzzi, which was depicted in the prelude to the novel Tragedy Day.
• The Timeless Children ^[+]Loading...["The Timeless Children (TV story)"]:
  • The actor for Rassilon was cast to resemble Don Warrington, who played Rassilon in the audio story Zagreus ^[+]Loading...["Zagreus (audio story)"].

• Revolution of the Daleks ^[+]Loading...["Revolution of the Daleks (TV story)"] marked the televised introduction of a Dalek death squad, which first appeared in the Dalek Survival Guide ^[+]Loading...["Dalek Survival Guide (novel)"].

Series 13

• Once, Upon Time ^[+]Loading...["Once, Upon Time (TV story)"]:
  • This story features the Siege of Atropos in which the Time Lords capture the Ravagers and allow the Mouri to control Time. This event is part of the anchoring of the thread that was first established in the novels Christmas on a Rational Planet ^[+]Loading...["Christmas on a Rational Planet (novel)"] and The Book of the War ^[+]Loading...["The Book of the War (novel)"].
  • A Weeping Angel emerges from Yasmin Khan's phone. The Angels had previously attempted to escape via mobile phone in the game The Lonely Assassins ^[+]Loading...["The Lonely Assassins (video game)"].
• In Village of the Angels ^[+]Loading...["Village of the Angels (TV story)"], Weeping Angels demonstrate an ability to hide inside solid rock, which they previously did in the audio Fallen Angels ^[+]Loading...["Fallen Angels (audio story)"].
• In The Vanquishers ^[+]Loading...["The Vanquishers (TV story)"], the Doctor encounters the embodiment of Time. The Virgin New Adventures had established that Time was a sentient being, specifically an Eternal. However, the episode conflicts with the novels since the Doctor says she had always wondered what Time looks like even though the Seventh Doctor had met Time in Lungbarrow ^[+]Loading...["Lungbarrow (novel)"].
• In Eve of the Daleks ^[+]Loading...["Eve of the Daleks (TV story)"], the Doctor remarks that she has not seen so much gunpowder since 1605. She and Yasmin Khan had witnessed Guy Fawkes' attempted destruction of Parliament in the short story Black Powder ^[+]Loading...["Black Powder (short story)"]. The First Doctor also became involved with these events in the novel The Plotters ^[+]Loading...["The Plotters (novel)"], as had the Eleventh Doctor in the video game The Gunpowder Plot ^[+]Loading...["The Gunpowder Plot (video game)"]. However, since all three stories conflcit with one another, the episode is most likely referencing Black Powder.
• The Power of the Doctor ^[+]Loading...["The Power of the Doctor (TV story)"]:
  • This story refers to Ace parting ways with the Doctor due to a falling out between them. While no details are given in the episode, a falling out did occur in the novel Love and War ^[+]Loading...["Love and War (novel)"].
  • The story also reveals that aspects of the Doctor's previous incarnations continue to exist in their mind after regeneration, something that had previously been explored in the novel Timewyrm: Revelation ^[+]Loading...["Timewyrm: Revelation (novel)"] and audio drama Zagreus ^[+]Loading...["Zagreus (audio story)"]. The concept is also prominent with the Big Finish character known as "the Eleven" (and other incarnations of the Time Lord) whose previous incarnations are retained following regeneration and frequently manifest and influence the actions of their successors.
  • The story also features a Type 75 TARDIS, which first appeared in the short story Going Once, Going Twice ^[+]Loading...["Going Once, Going Twice (short story)"].
  • Additionally, the story also features the Holo-Doctor, who debuted in the Seventh Doctor novel Infinite Requiem ^[+]Loading...["Infinite Requiem (novel)"].
  • Although not named as such, the story features the first televised retro-regeneration. The Doctor and other Time Lords had been subject to this concept numerous times in other media. Examples include the novels State of Change ^[+]Loading...["State of Change (novel)"] and Sky Pirates! ^[+]Loading...["Sky Pirates! (novel)"], the comic The Fountains of Forever ^[+]Loading...["The Fountains of Forever (comic story)"] and the audio The Lost Magic ^[+]Loading...["The Lost Magic (audio story)"].

This seems to be a reference to the novelisations of the story, Mission to the Unknown ^[+]Loading...["Mission to the Unknown (novelisation)"] and The Mutation of Time ^[+]Loading...["The Mutation of Time (novelisation)"], which add the Red Dalek Leader into the text in the place of an unnamed silver Dalek who commands the mission.

• The Giggle ^[+]Loading...["The Giggle (TV story)"]

  • The Toymaker boasts "Do you think a grand total of two can cause me to shiver when I've played against the Guardians of Time and Space [and won]?", implicitly taking it for granted that there are more than two Guardians. The idea of a wider pantheon of Guardians than the original TV portrayal's Manichean duo was first devised by Craig Hinton, and it was hinted at or stated in a number of sources including The Quantum Archangel ^[+]Loading...["The Quantum Archangel (novel)"] and Divided Loyalties ^[+]Loading...["Divided Loyalties (novel)"].
  • The Fifteenth Doctor refers to the death of Sarah Jane Smith, which was first established in the Doctor Who: Lockdown! webcast Farewell, Sarah Jane ^[+]Loading...["Farewell, Sarah Jane (webcast)"].

  • The UNIT file on Sarah Jane Smith is comprised of text copied exactly from UNIT History: Fighting the unknown ^[+]Loading...["UNIT History: Fighting the unknown (short story)"] from the U.N.I.T. website - this also, in turn, references the UNIT dating controversy, as it is referenced in the text of the story.
  • The story also features the appearance of an unnamed "Chief Inspector". In Gary Russell's novelisation, this inspector's name was given as Robert Lines, a policeman who had appeared several times in author Russell's novels and short stories.

Series 2

• The Temptation of Sarah Jane Smith ^[+]Loading...["The Temptation of Sarah Jane Smith (TV story)"] features the deaths of Sarah Jane's parents in a car crash. The fact that they died in a car crash was first established by The Roving Reporter ^[+]Loading...["The Roving Reporter (short story)"], a fictional biography of Sarah Jane published in the 1992 Doctor Who Magazine Holiday Special. However, some details differ, such as the year of the crash and her parents' names.

Series 3

• The Wedding of Sarah Jane Smith ^[+]Loading...["The Wedding of Sarah Jane Smith (TV story)"]:
  • Clyde Langer mentions that Sarah Jane's aunt had died before he met her.

  • The Trickster creates a time trap, trapping characters inside a single looped second of time.

• In Ian Chesterton: An Introduction ^[+]Loading...["Ian Chesterton: An Introduction (home video)"], the home video reconstruction of The Crusade ^[+]Loading...["The Crusade (TV story)"], Ian Chesterton recalls two untelevised adventures.

• In Liberty Hall ^[+]Loading...["Liberty Hall (home video)"], Alistair Gordon Lethbridge-Stewart mentions being with the Doctor in Malebolgia in 2003, which are references to the audio story Minuet in Hell ^[+]Loading...["Minuet in Hell (audio story)"].

• In Meet Doom - the Universe's Greatest Assassin! ^[+]Loading...["Meet Doom - the Universe's Greatest Assassin! (webcast)"], Doom reveals that she works for the Lesser Order of Oberon from the Time Lord Victorious series.

Other

There have been times when a reference to other DWU media was meant to appear in a live-action story but did not for various reasons. These include:

• The never-produced The Dark Dimension ^[+]Loading...["The Dark Dimension (unproduced TV story)"] would have featured a character named Summerfield who would be an alternate universe version of Bernice Summerfield from the Virgin New Adventures. Ace's name would be revealed as Dorothy McShane, just as it was in the novels.
• Planet of the Dead ^[+]Loading...["Planet of the Dead (TV story)"] would have featured the Chelonians from the Virgin New Adventures and Virgin Missing Adventures. However, the heat of the Dubai desert was thought to be far too intense for an actor in a turtle-like costume to endure.
• The Mad Woman in the Attic ^[+]Loading...["The Mad Woman in the Attic (TV story)"] was to have featured a clip from Downtime ^[+]Loading...["Downtime (home video)"] but Reeltime Pictures refused permission.
• The Day of the Doctor ^[+]Loading...["The Day of the Doctor (TV story)"] originally had Kate Stewart walk past posters for the Peter Cushing films while noting the need to screen the Doctor's associates.
