Doctor Who: The Doctor's greatest secret will "make viewers' jaws drop," says producer

There's plenty of Doctor Who news going around as we gear up for the show's return on March 30. Earlier this week, we were treated to four new movie-style posters for upcoming episodes (very exciting indeed), while yesterday we were treated to a rather humorous clip from the show's next episode, "The Bells of Saint John." Now, it appears, we've got some new scoop regarding the Doctor: he's got a very, very big secret. 

Now, it might be easy to assume that this secret is his name -- after all, that's the mystery the series has really been focusing on recently: "Doctor who?" has been described as being 'the final question.'

But Doctor Who's producers, playing their cards extremely close to the chest, are talking about a secret that doesn't seem to be the Doctor's name. In fact, they seem to be very deliberately hinting that it isn't. 

Whatever this secret is, producer Marcus Wilson has recently teased the secret as being pretty mindblowing. "It will make viewers’ jaws drop," he told TV & Satellite Week. "You thought you knew everything about the Doctor? Well, you never saw this coming."

That certainly could imply quite a few things, and it doesn't seem like there'd be too much to be gained from speculation. If you feel like you know what Wilson is talking about, though, please let us know in the comments section below. 

Wilson had even more to share, though -- most interestingly, regarding the show's 50th anniversary special. “[Showrunner] Steven [Moffat] has written a script that would make James Cameron weep. It’s a story that sprawls through space and time. It will be a huge epic," he is quoted as saying. James Cameron crying? You have my attention, Doctor Who.

Doctor Who will air "The Bells of Saint John" Saturday, March 31 on BBC One in the UK and BBC America in the US.
