On Christmas, December 25, 2010 the world’s longest running sci-fi TV series will air its sixth Christmas special with the Doctor Who: A Christmas Carol. In terms of where the episode sits in the chronology of Moffat’s tenure on the show, it picks up with Rory and Amy on their honeymoon, him in his Armour, her as a policewoman. Gambon is clearly having a lot of fun here, and makes for a strong Scrooge-like figure. And for those fearing Katherine Jenkins is stunt casting gone wrong, then fear not. The part fits her a treat, and even when she opens her mouth to belt out a song, you’re unlikely to mind. We’ve seen songs shoehorned uncomfortably into Doctor Who in the past, but not here. Murray Gold’s score tucks terrifically well around the many deliberately quiet and steady moments of the story, too. Really looking forward to this – the sets and lighting look fantastic. The Doctor Who: A Christmas Carol will star Matt Smith as the Doctor, Karen Gillan as Amy Pond, and Arthur Darvill as Rory Williams as well as guest starring Katherine Jenkins and Michael Gambon. The plot was based on the famous Charles Dickens’ novel, A Christmas Carol. Watch Doctor Who: A Christmas Carol and it will be aired on BBC-1 at 7:00 PM (BST).
