18 actors who have travelled between the universes of Harry Potter and Doctor Who
From the halls of Hogwarts to the Tardis, you wouldn't believe how many marvellous muggles have appeared in both...
Whether you're a devout Harry Potter fan or wholeheartedly Whovian, chances are you'll have noticed your favourite characters popping up in more than one universe.
The Boy Who Lived and the Time Lord appear to have quite a few friends in common. It's a small (acting) world after all, and you quite simply never know who you'll run into next.
Here are just some of the familiar faces who've managed to regenerate...
Tennant put in a terrific performance as Barty Crouch Junior. The Death Eater son of the Head of the Department of Magical Law Enforcement tried to bring about Harry Potter’s downfall in Goblet of Fire. Who was he in Doctor Who? The Doctor himself, of course.
Best known to an entire generation as Ron Weasley’s dad Arthur, Williams popped up in Doctor Who back in 2012 as Rory’s dad Brian. You’ll spot him in season seven episodes Dinosaurs on A Spaceship and The Power of Three.
Ron’s dad isn’t the only one doing the double: Harry Potter’s father James also pops up in both shows. Adrian Rawlins played the deceased wizard in the film franchise and lead the Ood rebellion as Dr Ryder in 2004’s Planet of The Ood.
