A big screen version of Doctor Who is in the works as part of David Tennant's deal to sign up for another season in 2010. A source told British paper The Telegraph: "For ages, BBC Worldwide held the rights and were planning to make a movie, but it got held up and former BBC1 boss Lorraine Heggessey decided to bring back the TV series in 2005. But everyone is keen now and the fans are clamouring. Part of David's conundrum is that he wants to do films, so this looks like it would solve both issues". Well, not really if he's playing the same role. Apparently outgoing producer Russell T. Davies revealed (to someone, anyway) he would like Catherine Zeta Jones to play the Doctor's companion in a film version, which would seem highly bloody unlikely. New producer Steven Moffat (who knocked back a chance to work with Spielberg to head up the new series) is also super-keen to see a cinematic outing for the time lord saying: "It would be good to see it in the cinema so long as it's fantastic."
