As a huge Doctor Who fan Christmas Day means more than stockings, turkey with all the trimmings, and opening presents. It means a brand new Doctor Who Christmas-themed episode. This year's episode is based on The Lion, the Witch, and the Wardrobe and sends our Doctor back in time to help a widow and her two children during the war. Here's a new clip from the episode to get us even more excited. Merry Christmas to us! It will air Christmas Day at 9/8c on BBC America!
