(Explaining why he isn't worried about the actor that will replace David Tennant in "Doctor Who" shortly after David's announcement he was leaving the show)
Russell: The next actor will sit there thinking it's 15 prime-time slots a year on BBC1. It's a great part, a great script - parts like that don't come along very often. I don't really think there will be a problem with the next Doctor being under too much pressure. Actors are clever and very ambitious - they have to be, just to be successful. A lot of actors will actually watch David and say 'I can do better than that' and they'll grab the chance to take over.
