Krampus

Krampus is a 2015 American Christmas comedy horror film based on the eponymous character from Austro-Bavarian folklore, directed by Michael Dougherty, and written by Dougherty, Todd Casey and Zach Shields. 

In the film, a dysfunctional family squabbling causes a young boy to lose his festive spirit.

As Krampus lays siege to the neighborhood, the family must band together to save one another from a monstrous fate.
