'Doctor Who': Ex-Time Lord shocker!

Are you a fan of Doctor Who? Then you need to stop what you’re doing — be it driving a car, flying a plane, or talking about how you didn’t sexually harass a member of your mayoral staff — and watch the just-released video below, which contains a big surprise and sets up the forthcoming 50th anniversary special show, which debuts November 23.

I’ll say no more, except that it does indeed feature a surprise appearance by a former Time Lord actor and…Argh, I’ve said too much already!
