The BBC's official Doctor Who Twitter account teased the guest stars appearing in the upcoming Christmas Special.
Peter Capaldi and Jenna Coleman will be joined by Nathan McMullen, Nick Frost (Hot Fuzz) and Michael Troughton, who is the son of Doctor Who star Patrick Troughton.
Nick comments: “I'm so thrilled to have been asked to guest in the Doctor Who Christmas Special, I'm such a fan of the show. The read-through was very difficult for me; I wanted to keep stuffing my fingers into my ears and scream 'No spoilers!' Every day on set I’ve had to silence my internal fan-boy squeals!"
Nick Frost's creative collaborator Simon Pegg (Shaun of the Dead) is no stranger to adventures in time and space. Pegg appeared in S1 episode The Long Game.
Steven Moffat, lead writer and executive producer, says: “Frost at Christmas - it just makes sense! I worked with Nick on the Tintin movie many years ago and it's a real pleasure to lure him back to television for a ride on the TARDIS.”
