Will David Tennant be involved in the Doctor Who 50th anniversary celebrations next year? Will there be a special episode bringing together his Tenth Doctor and one or more of the others? Of course, Tennant won't say.
But he has dropped a hint, telling an American interviewer that his trademark pin-striped suit is primed and ready to go, should he be called upon to don it once more.
Guesting on live US series Attack of the Show!, Tennant said of potential 50th anniversary plans "I cannot be drawn on anything. Who knows what will happen next year? I’m sure there are lots of plans being discussed in quiet rooms by men with long beards and grey hair.
"I’m not cofiming or denying anything."
But when asked whether he still had the Doctor's suit, Tennant replied "I do have it in a very secure location, yes.
"I have one of everything that I wore [on Doctor Who] in hermetically sealed suit bags, squirrelled away somewhere - I hope the moths haven’t got in."
Tennant also pondered the absence of the Time Lord during the Olympics torch relay and bemoaned the cutting of a Doctor Who scene from the opening ceremony. Watch the full interview below...
