An official photo from the upcoming DOCTOR WHO Christmas Special (set to transmit Christmas Day) has appeared on the show's official Facebook page.
The Doctor (Mattt Smith) is wearing a costume which strongly evokes the stylistic sensibilities of a few of the character's earlier incarnations, in an image which also recalls the increasingly intense and angry nature the Doctor has displayed in Season/Series 7 thus far.
As mentioned above, the Christmas Special (whose title has yet to be announced) will broadcast Christmas Day - the remainder of Season/Series 7 is said the be coming this Spring.
