The final scene of Doomsday vs. the same scene from The Runaway Bride
From the Runaway Bride commentary track with David Tennant and Julie Gardner:
Julie: There we have Donna entering your TARDIS
David: Interestingly, that sequence was the closing seconds of Doomsday
David: …which was the end of series two - but not those actual pictures. We re-shot it. We have two directors of photography on Doctor Who, Ernie and Rory. Ernie shot Doomsday in the way he likes to shoot the TARDIS and likes to light the TARDIS, which is lots of greens and lots of reds. Rory prefers it to be a more kind of golden affair
Julie: Yeah - a bit more yellow-y
David: Yeah, so the version of that scene would fit with the scene we’re now in [the rest of the Doctor/Donna initial scene in the TARDIS] we had to re-shoot it and do a kind-of Rory version of the scene.
Julie: and did you make different choices as an actor the second time?
David: No, in fact we had the dvd player by the side of the set to try to re-create it as exactly as we possibly could, so that you wouldn’t necessarily notice that it was different - although I just told you, so that gives that away
