Joss Whedon's 'Cabin in the Woods' Trailer Premieres

The long-delayed project starring Chris Hemsworth will open in theaters on April 13, 2012.

The Cabin in the Woods, the long-delayed horror film produced and co-written by Joss Whedon, finally got a trailer on Monday.

The Lionsgate film, starring Chris Hemsworth before he became famous as Thor, is about a group of friends who go on a retreat to a cabin in the woods, and some very bad things begin to happen.

While the trailer shows a lot, it doesn’t explain exactly what is coming after the attractive young people.  It’s clear that there is someone controlling the cabin, making bad things happen. As one person says in the trailer, “Somebody sent those things here to get us.”

It’s not clear what “those things” are exactly, but some of the creepy looking visuals in the trailer include: scary white masks, a strange forcefield, a dark creature rising out of a lake and an eerie looking cloud of dust.

“You’re missing the point. They want to see us punished,” says one character in the trailer.

Richard Jenkins, Bradley Whitford, Kristen Connolly, Brian J. White, Amy Acker, Fran Kranz and Jesse Williams also star in the long-delayed film.

While the horror film from Whedon and Cloverfield scribe Drew Goddard was originally set to release in 2009, it will finally make it to theaters April 13, 2012.
