Earlier today the official Doctor Who Twitter tweeted this picture of Cybermen on the set of Doctor Who season eight, and the BBC announced that Michelle Gomez (pictured on the right of Peter Capaldi) will be joining the cast as the Gatekeeper of the Nethersphere. Michelle Gomez is best known for her role as a deputy headmistress in the first two seasons of ongoing British sitcom Bad Education. She guest-starred in 2007 in the Doctor Who audio play Valhalla.
Showrunner Steven Moffat said, “I’ve known Michelle for years, and I’m thrilled to welcome her to Doctor Who. She’s everything we need – brilliant, Scottish, and a tiny bit satanic.”
