Today is Christmas Eve, and with now only a few hours left until Christmas Day is here, the BBC have added the twenty-fourth door to their online Doctor Who Advent calendar, only available on the official Doctor Who website. Inside today's door is a brand new and exclusive video, based upon the Weeping Angels who appeared in the tenth episode of Doctor Who series three, Blink, and who will later appear in an episode of the show's fifth series which will begin in Spring 2010. The video runs for approximately three minutes and ten seconds, and features the voice of John Barrowman, well known for his role as Captain Jack Harkness in both Doctor Who, and it's adult spin-off series, Torchwood. The video can be found exclusively inside door number twenty-four on the official Doctor Who website's Advent calendar by clicking here. The twenty-fifth door on the calendar will be openable from tomorrow, and some details regarding that will be posted here when the door is active. What do you think of today's Advent calendar surprise?
