Here’s a brand new clip from “The End Of Time, Part Two” which also marks the end of the David Tennant era of Doctor Who. This final tenth Doctor special airs in the UK on BBC One Friday, January 1st at 6:40 PM and in the US on BBC America January 2nd at 8:30PM. To paraphrase a previous regeneration, it’s the end once again, but the moment has been prepared for…

The Doctor faces the end of his life as the Master’s plans hurtle out of control. With the sound of drums growing louder, and an ancient trap closing around the Earth, the Doctor and Wilf must fight alone. But sacrifices must be made, and the deadly prophecy warns: “He will knock four times.”

David Tennant stars as the Tenth Doctor and guest stars include John Simm, Bernard Cribbins, Catherine Tate, Timothy Dalton, David Harewood and June Whitfield. “The End Of Time, Part Two” is written by Russell T Davies and directed by Euros Lyn. The producer is Tracie Simpson.
