A TV movie of the sci-fi series aired in 1996 before it was rebooted in 2005, and Moffat does not imagine a new big screen version will ever come to pass because his creative team would struggle with money, time, and who should play the title character.

There would also be creative clashes with the TV show as it is publicly funded by the BBC and cannot be transferred directly to the big screen.

He tells EW.com, "I don't think there is one... No one has ever squared the circle on that. How do we do this? How do we do it without leaching (sic) from the television series - which we're not allowed to do, because Doctor Who is public funded? If it's going to be a different Doctor, are we going to try and sell two Doctors at the same time? I know there's been loads of Doctors, but there's only been one at a time. You don't have a James Bond on television and one in the cinema. If he's the same guy, then when are we going to make that?

"We're talking one of the biggest TV shows in the world. It can't just be a medium-size movie - it's gotta be a colossal movie... I've sat with people, saying - and in the end it's not my decision or my choice, I don't own Doctor Who - 'Okay, explain to me how it's going to work'. And nobody has an answer."
