Filming has now been completed on this year’s Doctor Who Christmas special.

Written by Steven Moffat and directed by Douglas Mackinnon (Sherlock), the show’s eleventh Christmas episode will see Alex Kingston reprise her role as Professor River Song.

Special effects supervisor Danny Hargreaves ‏tweeted yesterday: “That’s a wrap!! Xmas special and series done!!! Awesome!!!!”

Kingston commented earlier this month: “Steven Moffat is on glittering form, giving us an episode filled with humour and surprise guest castings.”

The episode’s cast is also rumoured to include comedian Greg Davies and Little Britain star Matt Lucas.

The BBC’s synopsis for the episode reads: “It’s Christmas Day in the future and the TARDIS is parked on a snowy village street, covered in icicles, awaiting its next adventure. Time traveller River Song meets her husband’s new incarnation, in the form of Peter Capaldi, for the first time this Christmas.”

Alex Kingston will also return as River Song in 2016 for a series of brand new adventures from Big Finish, including an encounter with the Eighth Doctor (Paul McGann) in Doom Coalition 2.
