Joss Whedon's Cabin in the Woods Trailer Unleashed!

We get a glimpse of the Buffy mastermind's mothballed big-screen thriller, which is finally making its way to theaters

The trailer for Joss Whedon's long-delayed The Cabin in the Woods has finally hit the web.

And as you might guess by the title, it features a bunch of beautiful young people heading out to a far-flung vacation retreat only to find their lives in danger from an unknown evil.

So what can we expect?

While it's not the most original of plots, the fact this horror flick comes from the mind of the Buffy the Vampire Slayer and Firefly creator has to count for something, right?  After all, we see what appears to be a creature rising from a dark lake, a force field surrounding the woods, some masked baddies and a cabin that's obviously not what it seems.

Cabin, which Whedon directed from a script by Cloverfield scribe Drew Goddard, stars Chris Hemsworth, who took the role before he became famous in Thor, along with veteran actors Bradley Whitford and Richard Jenkins among others.

The movie was originally supposed to hit theaters in 2009 but was put on hold after MGM went bankrupt.  Lionsgate has since picked it up and will release it on April 13.
