Corrected entry: At the end of "World War Three" there is a side shot of The Doctor leaving the TARDIS in which you can see inside, but the control room isn't visible, just the side on the police box. In "The Runaway Bride" there is a shot from the same angle, but this time the control room is visible.Josman
Corrected entry: 2005 Christmas special, the Christmas invasion: A few times it is possible to see the Major's epaulettes. The symbol is a crown as in the British army. But seeing as Unit is a United Nations organisation (it stands for United Nations Intelligence Taskforce), an officer would have no reason to have a crown symbol on his epaulettes.
Corrected entry: Season 2: Episode 10 - Love and Monsters: Elton said that when he was young, he went downstairs and found the Doctor there. However, the Doctor has only looked like he does now for maybe a year or less because he keeps regenerating and changing his looks, so when Elton saw him he should have looked completely different.
