The first official trailer for The Cabin in the Woods, co-written by Joss Whedon (The Avengers), has been released.

Here’s a quick synopsis of the film:

A group of five friends going on a quiet cabin retreat scratch the surface of something so massive and horrific that they can only begin to fathom what might possibly be going on just as time quickly runs out.

The film, which is directed by Whedon-protege Drew Goddard, stars Chris Hemsworth (Thor), Richard Jenkins (The Visitor), Bradley Whitford (“The West Wing”), Jesse Williams (“Grey’s Anatomy”), Fran Kranz (Donnie Darko), Kristen Connolly (The Happening), and many more.
