Matt Smith faces a hellish holiday challenge in snippet from "Doctor Who" Christmas special

Merry Christmas, "Doctor Who"-style.

A new trailer has emerged for the upcoming special Christmas episode of "Doctor Who," dubbed "The Snowmen," and of course this won't be the typical diabetes-inducing holiday fluff.

"Doctor Who: The Snowmen" airs Dec. 25 at 9 p.m. on BBC America. Until then, stuff this in your stocking…
