The Doctor Who Christmas Special, which sees the return of Jenna-Louise Coleman, is scheduled against the final 15 minutes of ITV1's You've Been Framed! and 45 minutes of Emmerdale.
Steven Moffat's festive episode will be preceded on BBC One by BBC News and followed by Strictly Come Dancing.
Christmas Eve 1892, and the falling snow is the stuff of fairytales.
When the fairytale 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?
Starring Matt Smith, Jenna-Louise Coleman, Richard E Grant and Tom Ward.
Executive producers - Steven Moffat and Caroline Skinner; produced by Marcus Wilson; written by Steven Moffat.
