The BBC today opened the eighth door on their online Doctor Who Advent calendar, due to the fact that today is the eighth day of December. Inside today's door is a video interview with Phil Ford who recently wrote the second Doctor Who special, The Waters of Mars, and the animated Doctor Who adventure, Dreamland. In the short video interview, Phil Ford is asked what has happened to The Doctor's one-off companions from Dreamland, Cassie Rice, as voiced by Georgia Moffett, and Jimmy Stalkingwolf, as voiced by Tim Howar. The video interview can be found by clicking here inside today's door on the official Doctor Who website's Advent calendar. The ninth door, containing another brand new surprise, will be available to open exclusively online at the official Doctor Who website from tomorrow onwards. What do you think of today's new Advent calendar surprise?
