You know how catching the bouquet at the wedding is considered a "nice" thing? Well, you wouldn't want to get your hands on this one.

Today we exclusively reveal the poster to SXSW film pick "Honeymoon"; the synopsis alone gives me heebies.

Young newlyweds Paul (Harry Treadaway) and Bea (Rose Leslie) travel to remote lake country for their honeymoon where the promise of private romance awaits them.  Shortly after arriving, Paul finds Bea wandering and disoriented in the middle of the night. As she becomes more distant and her behavior increasingly peculiar, Paul begins to suspect something more sinister than sleepwalking took place in the woods.

Midnight selection "Honeymoon" is helmed by first-time director Leigh Janiak, who was impressed by Treadaway's performances in "Fish Tank" and "Control."

"What's interesting about Harry is that he has this masculinity that's not a typical 'dude' way and I'm drawn to that... when he read it, he really got that this wasn't a stereotypical 'I'm a man' role," Janiak said in our interview. She said the film definitely has a way of toying with gender roles, a "back and forth," and a play on "how well you can really know another person."

"Honeymoon" premieres at the Austin-based fest on Friday (March 7) at 11:45pm at the Alamo Drafthouse Ritz.
