The Exchange will be selling international rights to The Houses October Built at Cannes next week. The found-footage horror pic from New Regency and producer Steven Schneider (the Paranormal Activity andInsidious films) is about the Halloween haunted house phenomenon that draws more than 30 million visitors every year. It sheds light on a dark world of haunting that lurks beneath the surface of spooky fun. Zack Andrews and Bobby directed and produced the film, which has wrapped production. WME Global and Preferred Content are handling U.S. sales for the title.
