This is the trailer for an interesting looking thriller called Honeymoon. It comes from first-time filmmaker Leigh Janiak and stars Rose Leslie (Game of Thrones) and Harry Treadaway (Penny Dreadful). The trailer doesn't give much away, in fact, it's pretty mysterious, but I like the eerie tone of it.
Young newlyweds Paul (Treadaway) and Bea (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."
The film doesn't have distribution yet, but it will be showing at SXSX.
