Moffat on Day of the Doctor casting: Asked if it would have been Eccleston ending the Time War instead: “Yes, but do you know, I was always nervous of that one... [Eccleston] is a brand new Doctor in Rose... It couldn’t have been is who pushed the button in the Time War, cos that’s a new man, very explicitly, in that episode. I also had trouble, I have to be honest, imagining it being Paul McGann’s Doctor."
