10 Doctor Who Actors You Won't Recognise Out Of Costume

3. Paul Kasey

Name a Doctor Who monster and the chances are Paul Casey has played them. Not only has the actor been lucky enough to guest star in the main series and its two spin offs, Torchwood and The Sarah Jane Adventures, he's also the one actor who has appeared the most in the Whoniverse to date, with over 60 memorable roles to his name. It's funny, then, that you've probably never actually seen his face. He's been a big part of the series since its 2005 revival, though, as his momentous monster credentials include the likes of Autons, Clockwork Droids, Robot Santas, Ood, Judoon, pig slaves and Cybermen... to name but a few! What can he say? He dabbles.
