The BBC's official website for Doctor Who was today updated with the thirteenth door on their online Advent calendar. Inside today's door is the first part of a video, running for approximately two minutes, in which Louise Paige talks about working as costume designer on Doctor Who, and working with Billie Piper and Alex Kingston. The first part of the video can be found inside door thirteen on the official Doctor Who website's Advent calendar by clicking here, and the second part is expected to be released inside one of the remaining doors. Door number fourteen on the calendar will be made openable at some time tomorrow, and details regarding the content inside the door will be posted here shortly after. In news related to this website, this is my 500th post on The Gallifrey Vortex, so I would like to thank everyone who has visited, commented on my posts, and generally supported it. What do you think of today's brand new Advent calendar surprise?
