Actor David Walliams, famously known from the comedy series Little Britain and Come Fly With Me, and long time Doctor Who fan, has revealed on the BBC Radio 2 Breakfast Show that he will be appearing as an alien in an upcoming Doctor Who episode! He said: "I've actually been offered a part in Doctor Who, which I'm very, very excited about, I've said yes. I don't think I can say much, but I'll say I'm an alien." When asked if he would like to play a future Doctor one day he said: "I think any actor wouldn't turn that down. I won't be cast now though because they're getting younger."
