Speaking to Doctor Who Adventures in this week’s issue of the magazine, Gillan commented: “Oh, I’d definitely love to do more sci-fi – it’s really fun.”

Co-star Arthur Darvill added: “Yeah, but having done the best one it’s kind of hard to know what it would be. I’d love to come back as a monster or something!”

Gillan responded: “Yeah, I wanna be an alien! No one will ever know. I’ll be the one that’s facing the wrong way.”

Current companions Amy and Rory will depart Doctor Who later this year following “a final encounter with the Weeping Angels”.
