During a radio interview, Billie Piper(who played Rose Tyler in the series), spilled the news/rumor.
Thanks to The Daily Express:
“I’ve heard they’re doing a film and I know they want David to do it.
“I think David’s slightly anxious that there’ll be some big American producers on board and that they’ll try to hijack the whole thing and cast someone like Johnny Depp.”
Tennant is without a doubt my favorite actor to portray The Doctor, but I think its time for him to abandon the role completely. Tennant’s an amazing actor, but his whole career is pretty much based off of Doctor Who. In fact, the only other role he was in that I can remember was playing Barty Crouch Jr. in “The Goblet of Fire”.
Tennant’s probably busy doing jobs in America right now. He recently had to turn down a job with Simon Pegg because he was filming a pilot series for a legal series.
What Tennant needs to do is get a role that separates him from Doctor Who. He’s gonna have to do something spectacular for that, and going back into the role wouldn’t help at all.
Do you want Tennant to star in a Doctor Who film?
