Trailer: BBC Christmas 2012 - 'It's Showtime!'

The BBC have released their Christmas trailer for this year, highlighting some of the season's televisual treats. Being cynical, it's mostly exactly what we get the rest of the year only with added baubles, tinsel and garish jumpers. But there is the Doctor Who Christmas Special to look forward to, of course--plus Restless with Rufus Sewell and Downton Abbey's Michelle Dockery. Does anything else here take your fancy?
