Here's the episode's synopsis:
This Christmas sees the Doctor join forces with a masked Superhero for an epic New York adventure. With brain-swapping aliens poised to attack, the Doctor and Nardole link up with an investigative reporter and a mysterious figure known only as The Ghost. Can the Doctor save Manhattan? And what will be revealed when we see behind the mask?
Peter Capaldi stars as the Doctor, Matt Lucas (Bridesmaids, Little Britain) as Nardole, Justin Chatwin (Orphan Black, Shameless) as Grant and Charity Wakefield (Wolf Hall, The Player) as an investigative journalist.
The special is written by Steven Moffat, executive produced by Brian Minchin, produced by Peter Bennett and directed by Ed Bazalgette (Poldark).
