Joss Whedon and Drew Goddard have signed on Kristen Connolly (Revolutionary Road), Chris Hemsworth (Star Trek), Anna Hutchison, Fran Kranz (The Village) and Jesse Williams (The Sisterhood of the Traveling Pants 2) for their genre-bending horror film Cabin in the Woods.

According to The Hollywood Reporter, the United Artists film had already cast Richard Jenkins and Bradley Whitford.

The genre-tweaking screenplay was written by Whedon, who is producing, and Goddard, who is directing. The plot and character descriptions have been withheld by the filmmakers and the studio.

"Finding this ensemble has been very hard and very rewarding," Whedon said. "Each of the 'kids' is unique, fascinating and talented, and like true friends, the group is more than the sum of its parts. These are people you care about, able to go toe to toe with the amazing actors we've corralled thus far, and not unpretty in the bargain. I can't wait to harm them."

The film is already shooting, though its release date has been pushed back from Oct. 23 to Feb. 5. Presumably, this is to plant a flag in the date-night terrain of Valentine's Day and avoid competing with a potential Saw VI release before Halloween. MGM will distribute.

The Cabin in the Woods comes to theaters April 13th, 2012 and stars Richard Jenkins, Bradley Whitford, Jesse Williams, Chris Hemsworth, Fran Kranz, Kristen Connolly, Anna Hutchison, Brian J. White. The film is directed by Drew Goddard.
