Doctor Who executive producer Steven Moffat has ruled out any chance of a movie version of the sci-fi series.
Speaking to Entertainment Weekly Moffat said: "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 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?"
"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."
Doctor Who will return for a ninth series on BBC One later this year.
