Festive romance is in the air for Doctor Who and his new companion Love is in the air for the stars of the Doctor Who Christmas Day special. The Snowmen sees the Timelord, played by Matt Smith, reunited with his new companion, played by Jenna-Louise Coleman. The actress, who made a surprise appearance in an earlier episode Asylum of the Daleks, admitted the Christmas Day show was a "bit of a love story," but with a "quite dark" edge. She said: "I think there is definitely a romantic tone to this particular episode." Smith added: "It can change every week, that's the beauty of it. One week it's a love story, one week it's an action adventure. The episode, written by show supremo Steven Moffat, is set on Christmas Eve 1892 and sees the Doctor up against an army of snowmen led by the villainous Doctor Simeon, played by Richard E Grant. Moffat said there was something inherently festive about the Timelord. He said: "Doctor Who is the story of an alien wizard who comes to help people in need, so you instinctively think he is best mates with Santa Claus, don't you? You do think the two of them belong in the same world and have a drink together occasionally. The writer, who is also responsible for the hit re-imagining of Sherlock, stayed tight-lipped about plans for the fiftieth anniversary of the show next year - apart from promising it would be "immense." But Smith did admit to a name for a dream co-star for an anniversary special, saying: "Let's just go all out there - I'm going to say Javier Bardem." He said Bardem, who played the villain in the last Bond film, would be "a really brilliant Doctor."
