The BBC have confirmed three guest stars for this year's Christmas Special:
Nick Frost - well known for starring in films with Simon Pegg such as "Shaun of the Dead", "Hot Fuzz" and "Paul".
Nathan McMullen - best known for his role as Finn Samson in Channel 4's "Misfits".
Michael Troughton - does he really need an introduction? Apart from the obvious connection, his most well known role was probably as Piers in "The New Statesman". He has, of course, starred in a number of Big Finish audios.
The BBC press release reads:
Production on 2014's Doctor Who Christmas episode has begun, with a host of British acting talent set to appear. The Christmas special, a cracker of a highlight in the festive season’s schedule, will air this Christmas on BBC One and promises to be an action-packed, unmissable adventure.
Nick Frost, actor and screenwriter, has starred in numerous hit film and television roles, including Spaced, The World’s End, Shaun Of The Dead, Hot Fuzz, Cuban Fury and Paul, which he also wrote.
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!"
Michael Troughton (Breathless, The New Statesman), who has recently returned to acting, will follow in his father’s footsteps by appearing in Doctor Who. His father, Patrick Troughton, played the second incarnation of the Doctor.
They will be joined by Natalie Gumede (Coronation Street, Ideal, Strictly Come Dancing), Faye Marsay (Pride, The White Queen, Fresh Meat) and Nathan McMullen (Misfits, Casualty).
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.”
The Doctor Who Christmas Special will air on BBC One. Written by Steven Moffat and directed by Paul Wilmshurst (Strike Back, Combat Kids), it will be shot in Cardiff at BBC Wales Roath Lock Studios.
