Watch The Epic 'Doctor Who' Christmas Special Trailer!

Break out the tissues, put on your Christmas crown and prepare for Matt Smith's final outing as the Doctor. The trailer for this year's "Doctor Who" Christmas Special titled "The Time of the Doctor" has arrived.

The "Doctor Who" Christmas Special is always a special occasion. This year it's even more so as Whovians say goodbye to Smith -- the Eleventh Doctor -- and Peter Capaldi steps into the role of the iconic Time Lord.

The trailer shows the Doctor, and his companion Clara (Jenna Coleman) battling Cybermen, Daleks and Weeping Angels in a snowy Christmas setting.

"The Time of the Doctor" will air on BBC America on Dec. 25 at 9 p.m. EST.
