History Trivia / DoctorWhoS21E6TheCavesOfAndrozani

** Creator/WarrenClarke was considered for Stoltz.
** Creator/StevenBerkoff was considered for Sharaz Jek, Stoltz and Chellak.

* CastTheRunnerUp: Christopher Gable (from the Creator/KenRussell film adaptation of ''Theatre/TheBoyFriend'') was originally offered the role of Salateen. Creator/GraemeHarper wanted him for Jek but didn't think he would accept, as he'd be hidden behind a mask for the whole story (except for the hideous prosthetics of the ''[[Literature/ThePhantomOfTheOpera Phantom of the Opera]]'' reveal); but Gable wanted the challenge and the larger role.

* CreatorChosenCasting: Creator/GraemeHarper always had Christopher Gable in mind for Sharaz Jek.

** Music/DavidBowie was originally lined up to play Sharaz Jek, only for his manager to turn down the BBC's request due to the scheduled taping dates overlapping with the supporting tour for ''Music/LetsDance''. Other actors considered for the part included Creator/TimCurry, Music/MickJagger, Creator/DerekJacobi, and Creator/JohnHurt (the latter two would go on to appear in the Revival Series decades later as the Master and the War Doctor, respectively); Creator/GraemeHarper stated that while he always had Christopher Gable in mind for Jek and was pleased with his performance, he felt that Bowie was the only other celebrity who would've fit in the part.

** The first scene would have featured the Doctor and Peri at the opening of the story in the TARDIS. The Doctor was to explain to Peri the reason for their visit to Androzani Minor. Apparently, as a boy, the Doctor had started a "blown glass bottle collection", which was made from the sand of different planets. He had lost his Androzani bottle and decided to return there to retrieve some more sand. It was in this scene Peri was to say "You're such a pain, Doctor." However, when the final cut of the serial was made, it had been discovered that certain lines of dialogue (like the Doctor professing that "I am not a pain" and Peri's comments about needing sand to "make some glass") alluded to the cut sequence. To rectify this, Creator/PeterDavison and Creator/NicolaBryant voiced over part of their conversation while the TARDIS materialises from outer space to the planet.

* ThrowItIn: The scenes where Morgus faces the camera directly and speaks out his inner thoughts came about from John Normington misunderstanding the stage directions he was given. However, everyone liked the theatrical feel of the technique and kept it in the episode.

* WriterRevolt: This serial is often interpreted as Holmes criticising the nihilism and violence of the Creator/EricSaward era by saying "[[IWillShowYouX You want grim violence? I'll give you grim violence!]]". Holmes dumps the Doctor in a brutal world of EvilVsEvil where all he and Peri can do is try to survive, but in contrast to many stories of Saward's era, which made the Doctor a [[PinballProtagonist passive and ineffectual figure]], "...Androzani" emphasises the Doctor's [[{{Determinator}} bravery, determination and self-sacrifice,]] as well as his [[DeadpanSnarker wit]].

** The second scene to be cut would have featured the Doctor battling with the magma beast in Episode Four which, [[SpecialEffectsFailure under the circumstances, the serial is probably better off without]].

* ThrowItIn: The scene where Morgus faces the camera directly and speaks out his inner thoughts came about from John Normington misunderstanding the stage directions he was given. However, everyone liked the theatrical feel of it and that take was left in the episode.

** Creator/TimCurry, Music/DavidBowie and Music/MickJagger were offered the role of Sharaz Jek. Also considered were Creator/DerekJacobi and Creator/JohnHurt (both of whom would go on to appear in the revival series decades later as the Master and the War Doctor, respectively). Of these five, David Bowie is the only one whose refusal we actually know the reason for: the scheduled taping dates conflicted with [[Music/LetsDance his Serious Moonlight tour]].

* BillingDisplacement: Colin Baker receives top billing, above Peter Davison, for the final episode, despite only appearing for 20 seconds at the end of the episode.

** The second scene to be cut would have featured the Doctor battling with the magma beast in episode four which, [[SpecialEffectsFailure under the circumstances, the serial is probably better off without]].

* DeletedScene: Recording was interrupted by a strike, which caused a serious delay in the filming of the serial. As a result, two sequences had to be cut. The first scene would have featured the Doctor and Peri at the opening of the story in the TARDIS. The Doctor was to explain to Peri the reason for their visit to Androzani Minor. Apparently, as a boy, the Doctor had started a "blown glass bottle collection", which was made from the sand of different planets. He had lost his Androzani bottle and decided to return there to retrieve some more sand. It was in this scene Peri was to say "You're such a pain, Doctor." However, when the final cut of the serial was made, it had been discovered that certain lines of dialogue (like the Doctor professing that "I am not a pain" and Peri's comments about needing sand to "make some glass") alluded to the cut sequence. To rectify this, Creator/PeterDavison and Creator/NicolaBryant voiced over part of their conversation while the TARDIS materialises from outer space to the planet. The second scene to be cut would have featured the Doctor battling with the magma beast in episode four which, [[SpecialEffectsFailure under the circumstances, the serial is probably better off without]].

* CreatorsFavoriteEpisode: Creator/PeterDavison named this as his favourite serial (claiming that if he'd gotten more stories of this quality earlier in his run he would have wanted to stay on longer), Creator/NicolaBryant named it as her favourite from her first series and Creator/JohnNathanTurner named it as one of the highlights of his tenure.

** Creator/GraemeHarper hoped to bring Creator/MichaelCraze back to play Krelper, only to be vetoed by Creator/JohnNathanTurner, who had felt that casting Jacqueline Hill in "Meglos" three years previously had been a mistake and decided not to cast former regulars in unrelated guest parts again.

* EnforcedMethodActing: This story was rife with on-screen mishaps that ended up causing minor injuries to Creator/PeterDavison, who would later jokingly claim that the staff were actually attempting to kill him.

** Creator/MartinJarvis and Creator/MichaelJayston were considered for Sharaz Jek and Morgus. The former would later appear in "[[Recap/DoctorWhoS22E2VengeanceOnVaros Vengeance on Varos]]" and the latter would later appear as The Valeyard in Season 23.

** Creator/MartinJarvis was considered for Sharaz Jek and Morgus.

* TroubledProduction: This was one of several eighties stories affected by strike action at the BBC (in this case, by the scenery shifters). It lost one of its studio sessions, and one of the sessions for the following serial, "The Twin Dilemma", had to be reassigned to it (which might have resulted in the cancellation of "Dilemma", although in the event John Nathan-Turner was able to secure an extra slot for that story on the grounds that it was important as the new Doctor's first full story; however, it also contributed to the poor working climate that resulted in "Dilemma" being recklessly rushed out the door).
