He may be best known for his role in Desperate Housewives, But Ryan Carnes will soon burst onto our TV screens in episode 4 and 5 of the newest Doctor Who series.

Ryan told The Sun:

“Filming was so much fun!

“I literally got the call from my agent in the middle of the night saying ‘Pack your stuff, you’re going to Wales’.

“I was whisked off and spent five weeks filming there.”

He couldn’t give too much away about the storyline, but he did reveal:

He said: “I play a young guy who’s met the love of his life.

“The couple are at that stage of the relationship where they can’t get enough of each other - but then suddenly something strange happens.”

He laughs: “I sort of become a pig. I get caught between the human realm and the swine realm.

“It kind of throws a wrench into the relationship.”

He added: “David Tennant was wonderful to work with, a true pro.

“It was clear to me why he is so successful and why he’s got such a following.

“He has an easiness about him, he is so laid back. Oh, and completely ego-less.”
