Fans of "Doctor Who" are likely still reeling from last night's season finale so the producers were wise to also drop a teaser clip for the upcoming Christmas Special. Forget about peace and good will when you're talking about the time-traveling Doctor who has a knack for finding turmoil at every turn. Peter Capadi just completed his first full season as the title character and the results have been mixed. It seems any negativity about this season was in the content rather than in Capaldi's acting abilities. He certainly portrayed the Time Lord as a bit harried and always looking at the bigger picture.

There are also some rumors that Jenna Coleman's time on the show may end with the Christmas episode. If that's the case then it'll be a sad ending to their first season working together. As Clara Oswald, Coleman has been an interesting companion for the Doctor. She also proved her worth and devotion in the season finale by pointing out that he is the one person that she will never lie to or turn against. The series has really gotten their money's worth out of Coleman, let's hope that they find a way to keep her around for a bit longer.

Check out the teaser for the "Doctor Who" Christmas special below. It features guest stars Michael Troughton (son of Second Doctor Patrick Troughton), Natalie Gumede, Faye Marsay, Nathan McMullen, and Hot Fuzz star Nick Frost, who is playing Santa Claus.
