It's been a huge year for Doctor Who, and after all the excitement of the 50th anniversary celebrations, the show looks set to end 2013 with a bang in its special Christmas Day episode.
Christmas time will see the departure of Matt Smith, as new doctor Peter Capaldi takes over the Tardis. There to help him settle in will be the Doctor's assistant Clara Oswald, played by Jenna Coleman.
