Doctor Who: The Snowmen - Synopsis and Trailer

Christmas means one thing - or rather, one thing in my Universe - and that's the Doctor Who Christmas special. Admittedly, there's all that stuff about family and friendship and peace and goodwill to all men etc., but it's mostly about Doctor Who.

This year's Christmas special, The Snowmen, is a chilling tale about  monstrous snowmen with razor-sharp teeth, and not to be confused with The Snowman, the heart-warming story of Aled Jones and his snowy companion.
Here's the BBC's official summary...

Christmas Eve 1892 and the falling snow is the stuff of fairy-tales. When the fairy-tale becomes a nightmare and a chilling menace threatens Earth, an unorthodox young governess, Clara, calls on the Doctor for help. But the Doctor is in mourning, reclusive and determined not to engage in the problems of the universe.

As old friends return, will the Doctor really abandon humankind or will he fight to save the world – and Christmas – from the icy clutches of this mysterious menace.

The Snowmen sees the introduction of Jenna-Louise Coleman as the Doctor's latest companion, Clara, and will also guest star Richard E. Grant and the voice of Sir Ian McKellen. The episode will also feature some new aesthetics, with a new title sequence, a new outfit for the Doctor and a sleek new TARDIS interior which harkens back to the style of the classic Doctor Who series (presumably as an homage as Doctor Who the year of its 50th anniversary).

The Snowmen is billed for the slightly earlier time of 5.15pm on Christmas Day, and the trailer can be found immediately below this sentence.
