'Doctor Who' Christmas Special 2014 Trailer Features Nick Frost as Santa! (VIDEO)

We're just about two weeks away from the 2014 Doctor Who Christmas Special! But what dangers will "Last Christmas" have in store for The Doctor (Peter Capaldi) and Clara (Jenna Coleman)?

Well, whatever those dangers end up being, it looks like they'll be getting help from jolly ol' St. Nick himself: Nick Frost, that is. The Shaun of the Dead star plays Santa Claus, because of course a Time Lord who's been alive for nigh on a thousand years would turn to a mythical being who's practically ancient himself (if nothing else, they can trade stories on unconventional means of conveyance).

But what is the threat? Will Clara really be the same after the events of the Season 8 finale? And will The Doctor ever not come across as though he's enjoying the hell out of all this danger? Check out the trailer for the Doctor Who Christmas Special, "Last Christmas," below:
