WATCH: Jennifer Aniston Gets Crazy In The Trailer For Her New Film 'Office Christmas Party'

We assume there's a good reason she slams a guy's head into a pool table.

It's July, so obviously we're due another Christmas movie, right? Right??

But here's the thing: this one looks pretty damn good. It's called Office Christmas Party and the trailer has just dropped.

Not only is Jennifer Aniston in it, it's also got a fine cast drawing from the best of Comedy Central and the comedy WORLD. 

We're talking T.J. Miller, Jillian Bell, Jason Bateman, Kate McKinnon, Olivia Munn, and more more more.

Why is she smashing that guy's head against a table? When did she get so badass? What's her DEAL?

This looks awesome, tbh. And any film with the tagline HO HO HOLY $#!T must be worth giving a red hot go.

Check out the trailer below.
