In preparation for Christmas and the premiere of this year's remaining Doctor Who specials, the BBC's official Doctor Who website launched their online advent calendar for 2009 earlier this month. The advent calendar will feature many exclusive treats over the next three days and door number twenty two on the calendar is now available to open due to the fact that today is the twenty second of December. Behind today's door, there's a new behind the scenes WhoSpy feature for the 10th Doctor's final adventure, The End of Time. You can view these new images here whereas content from behind the calendar's previous doors can be found here. This year's twenty third door on the calendar will be available to open sometime tomorrow and details regarding the next special advent treat will be posted on this site soon. What do you think of these new behind the scenes images?
