History Trivia / DoctorWhoS30E17E18TheEndOfTime

* RealitySubtext: The Doctor complaining about the "WORST! RESCUE! EVER!" is even more justified when one considers that Creator/DavidTennant had just recovered from surgery to repair a back injury sustained during his run on ''Hamlet'' at the RSC in-between shooting his final seasons; the crew ended up using a dummyfor the long shots of the Doctor going down the stairs to avoid the risk of re-injuring him, as well as camera tricks in the close-ups, but Tennant's [[ThisIsGoingToSuck visible discomfort]] is [[EnforcedMethodActing still readily apparent]] given he still ended up doing multiple takes of the sequence anyway. Bernard Cribbins jokes that they had to keep him away from Tennant, [[CrossesTheLineTwice or else he'd have pushed him down the steps even faster.]]

** Creator/RussellTDavies originally wanted to have the Doctor and the Master swap bodies. However, Davies wasn't keen to spend time during Creator/DavidTennant's final story with the actor playing anybody other than the Doctor, and was also mindful that he had used a similar notion in "[[Recap/DoctorWhoS28E1NewEarth New Earth]]".

** Davies originally considered having the Time Lords in an alliance with the Daleks to show how they had been corrupted. However, Creator/StevenMoffat was also planning to bring back the Daleks and expressed his preference for this to be the first Dalek story in a while. Keen not to undermine his successor's first season, Davies abandoned the notion.
** There was originally a scene where the Doctor actually met Trinity Wells, the American news anchor who had appeared intermittently ever since "[[Recap/DoctorWhoS27E4AliensOfLondon Aliens of London]]". Davies was eager to give Lachele Carl a proper appearance in the series, but ultimately dismissed the sequence as too self-indulgent.

** One prominent element dropped from the script was a subplot in which the Doctor tries to convince the "Danes-Master" (that is, the copy of the Master who had been Danes, the Naismiths' butler) to rebel against the evil Time Lord.

** Davies's book ''The Writer's Tale'' revealed that the mysterious Woman who appears throughout the episode, and later gives the Doctor a clue as to how to defeat the Time Lords once and for all, is the Doctor's mother.

* WagTheDirector: Creator/DavidTennant disliked the original take of the Tenth Doctor's last words, where the Doctor was really turning on the waterworks as he uttered them, believing it came across as a little too unheroic and was unbecoming of the character, and he didn't want it to be the note his version of the Doctor went out on. Tennant managed to argue for a slight change to the scene, which was the one that ended up on-screen, where the Doctor is clearly emotionally affected by his incoming regeneration, but also manages to remain somewhat calm and collected, in spite of it.
** This is slightly inaccurate to how it went down on set ([[https://www.youtube.com/watch?v=qWM7l9SAipg see here]]). They shot four versions of The Doctor's last words, increasing the emotion each time, with The Doctor breaking down and crying on the fourth and final take. Director Euros Lyn figured he'd use the final take, but all parties on set agreed it was a bit too much. Tennant argued for the third take, feeling that The Doctor being obviously emotional but trying to maintain his composure felt more in-character.

* PropRecycling: The two Raxacoricofallapatorians at the bar are the new Slitheen costumes created for ''Series/TheSarahJaneAdventures'' rather than the old ones from Series 1. Notably, "The End of Time" was filmed before but broadcast after SJA's [[Recap/TheSarahJaneAdventuresS3E11E12TheGift The Gift]], where the Slitheen costumes were painted orange to serve as Blathereen.

** June Whitfield really did get a handful of Creator/DavidTennant's bum. Repeatedly. For the ''realism!''

* ActingForTwo: Actually, Acting for ''over Six Billion'' — Creator/JohnSimm, primarily through {{chroma key}}s and a lot of costume changes.

** Omega was originally going to appear instead of Rassilon, but the idea was dropped.

* WorkingTitle: ''The Immortality Gate'' and ''The Final Days of Planet Earth'' for Part One (with the second part initially being called ''The End of Time''). Davies came to dislike the latter when he saw it onscreen, and felt the scale of the story required using "Part One" and "Part Two".
