The Christmas special brings a new companion and a new interior for the TARDIS. We got the first glimpse of the new interior about a week ago when we saw the top image with the Gallifreyan writing. Now The Doctor himself is showing off the rest of it.
In the 2006 Christmas Special, "The Runaway Bride," the doctor created a diversion by causing an ATM to spit out money. The prop money used in the show were 10-pound notes with David Tennant on them and 20-pound notes with producer Phil Collinson on them. Now the BBC is letting you print out your own.
