With San Diego Comic-Con now in full swing, Matt Smith has been the latest to do a Q&A at the event, and you won’t be surprised to hear that no shortage of Doctor Who questions were fired his way.

Smith has just finished filming How To Catch A Monster, which is being directed by Mr Ryan Gosling. And he admitted that “Doctor Who has been the most brilliant experience for me as an actor and a bloke, and that largely is down to the cast, crew and fans”.

Smith was asked how he’d like his incarnation of the Doctor to come to an end, and he replied that “I feel like I already know how it ends. There’s a golden light, open a TARDIS, put my arms out… and then I turn into a woman!”

You don’t need us to tell you that there’s no shortage of speculation that a female Doctor is around the corner, although we’d still be surprised if it was. However, Smith told IGN that “He’s an alien, or she’s an alien. It doesn’t matter. The Doctor is a complete alien … It can be anyone – and that’s the great thing about the part”. “There’s so many female actresses who’d be amazing”, he said, citing Helen Mirren as one example.

Matt Smith did admit that he didn’t know who the 12th Doctor was yet. Not that he’s likely to tell if he knew otherwise, of course. “You’re in for some serious revelations”, he teased when asked about John Hurt and the 50th anniversary Doctor Who special. The Christmas special, meanwhile, is set to shoot in September.

Smith also suggested that he’d been interested in roles in Star Trek and Star Wars, too.

The full Doctor Who Comic-Con panel is scheduled for Sunday. Expect more speculative questions around then…
