Rumours have been flying around once more about a Doctor Who movie after, in an interview, Billie Piper seemed to hint that there might be one. While talking to Sara Cox, she said:
"Well, I’ve heard that they’re doing it and that they want David to do it, but I think he’s slightly anxious that there’ll be big American producers on board and that they’ll try and hijack the whole thing and cast someone like Johnny Depp."
Sounds interesting! Nothing has been confirmed at the moment, but it's a nice thought! Thanks to WhovianNet for this information.
