Sci-fi fans have a new Christmas tradition: the annual “Doctor Who” holiday special. This year’s special, “The Snowmen,” promises to be even more of an event than usual as it marks the official introduction of the Doctor’s brand new companion Clara (Jenna-Louise Coleman).

The Doctor himself, Matt Smith, joins Coleman in letting fans know what to expect in this final teaser for the special, premiering Dec. 25 on BBC America in the U.S.

While Smith teases a “new version” of the Doctor, it’s obvious from the genuine chemistry between Smith and Coleman that little will change when it comes to the show’s trademark fun and banter.

In prepration for spending your holiday with the Doctor, don’t forget to check out the “Snowmen” prequel webisode and trailer, as well as our collection of photos from the episode.
