Yesterday we gave you a tease of Krampus with a look at the first photos. The upcoming holiday horror movie from Trick 'r Treat's Michael Dougherty is due out this December and we now have the first trailer for you to watch.

Legendary Pictures’ Krampus, a darkly festive tale of a yuletide ghoul, reveals an irreverently twisted side to the holiday.

When his dysfunctional family clashes over the holidays, young Max (Emjay Anthony) is disillusioned and turns his back on Christmas.  Little does he know, this lack of festive spirit has unleashed the wrath of Krampus: a demonic force of ancient evil intent on punishing non-believers.

All hell breaks loose as beloved holiday icons take on a monstrous life of their own, laying siege to the fractured family’s home and forcing them to fight for each other if they hope to survive.

The horror-comedy also stars Adam Scott, Toni Collette, David Koechner, Allison Tolman, Conchata Ferrell, Stefania Lavie Owen and Krista Stadler.

Krampus and his mischievous underlings have been created by the combined efforts of Weta Workshop and Weta Digital, both renowned for their epic work on The Lord of the Rings and The Hobbit trilogies and King Kong, among many others.

Written and directed by Michael Dougherty (Trick ’r Treat), Krampus is co-written by Zach Shields and Todd Casey and produced by Legendary’s Thomas Tull and Jon Jashni, Alex Garcia and Dougherty.  The film will be released by Universal Pictures.

Starring Adam Scott, Toni Collette, Emjay Anthony, Allison Tollman, Stefania Owen, and David Koechner, Krampus was directed by Michael Dougherty from a screenplay he co-wrote with Todd Casey and Zach Shields. A Legendary Pictures film, Krampus is slated for a December 4th release from Universal. We've included an update to our photo gallery below with new images and high-resolution versions of all photos.
