Samuel Anderson (of The History Boys) will be playing a character named Danny Pink.
"I was so excited to join Doctor Who, I wanted to jump and click my heels, but I was scared I might not come down before filming started!" he said.
"It's a quintessential part of British culture and I can't believe I'm party of it. It's an honour to be able to work alongside Peter Capaldi and Jenna Coleman and I can't wait to show people how my character becomes involved with such a fantastic duo!"
Moffat is still showrunner, so I'm horrified. But I hope I'll be pleasantly surprised.
Anderson's quote is adorable, though.
