Character mistake: Idris (the human form of the TARDIS) berates the Doctor because the doors of the TARDIS open inwards, pointing to the notice on the left hand door which says 'pull to open'. Whilst it is true that police boxes did open outwards, the notice is actually referring to the telephone in the small recess behind the notice. The public are instructed to 'pull to open' the small door to access the phone. Consequently, the small door does open correctly, as in the notice. (00:23:50)

1 character mistake in season 6 - chronological order
Continuity mistake: Before Martha uses Project Indigo, she doesn't have an ear piece. Then, after two quick shots of Daleks, when Martha says, "Bye, Jack," she does (and then takes it out). (00:17:56)

Rise of the Cybermen (1) - S2-E8
Trivia: Only eleven Cybermen costumes were built, but careful filming made it look as if there were more.
Question: 1. Why was Rose not allowed to touch her past self without creating a paradox and causing those creatures to appear and eat everyone, but Amy was allowed to touch her younger self without any repercussions? 2. Why was Rose able to have the time vortex in her head for a few minutes and it only knocked her unconscious whereas the Doctor had it inside him for about 30 seconds and it basically killed him and caused his regeneration?
Chosen answer: 1) When Stephen Moffat took over he ignored a lot of what had been developed before (there is not in-universe answer). 2) It would have killed Rose, so the Doctor absorbed the energy. His body regenerated before the energy could do a significant amount of damage that would prevent regeneration.
