The Cabin in the Woods

One big clue about Joss Whedon’s Cabin in the Woods

We’re still trying to find out more about The Cabin in the Woods, but co-star Amy Acker (Dollhouse) let slip a clue at WonderCon in San Francisco over the weekend. (Spoiler ahead!)

The horror a movie, co-written by Buffy the Vampire Slayer creator Joss Whedon and director Drew Goddard, was supposed to come out this past February, but now they’re converting it into 3-D, so it won’t be out until January 2011.

But though Whedon and Goddard have been tight-lipped about the plot details, Acker let slip that Cabin in the Woods is a creature feature. "There’s a lot of scary monsters," Acker said in a group interview while promoting the upcoming ABC TV series Happy Town. "It’s a scary movie."

The film is officially finished, Acker said: Not the 3-D coversion, but the "picture locked" edit. "I got an e-mail yesterday that it was finished," Acker said. "The cut is finished, so they’ve got it all, well, ’in the can’ I guess is what the terminology was."

She hasn’t seen it yet, but her Happy Town bosses have. "These guys are all friends with Drew from Alias [in which Acker also had a role], and they saw it and said that it was awesome," she said. "So that’s good."

Is this movie really such a mystery, though? I mean, the title is The Cabin in the Woods. "It is about a cabin in the woods," Acker confirmed. "You’ve figured it out. Yeah, it’s about a cabin in the woods. It does take from the sort of formula of the horror movie of this group of young kids who go away to a cabin in the woods for the weekend, and everything that happens and what you think is supposed to happen."

The Cabin in the Woods is due in theaters Jan. 14, 2011.
