Starring in The Snowmen, we have Richard E Grant, Tom Ward, and the delectable Jenna-Louise Coleman, who's not going to roar "Doctor, explain to me what's going on?!?" in a Scottish accent every nanosecond. Welcome, Ms Coleman.
You can catch this highly anticipated Christmas Special on BBC1 Christmas Day at 5.15pm.
Make sure it doesn't clash with turkey time.
