According to The Hollywood Reporter, Warner Bros. Pictures has pre-emptively picked up the spec script The Dionaea House by Eric Heisserer for David Heyman to produce via his Heyday Films banner.
The story follows a married man who has grown apart from his old friends. When one of them commits a double-murder suicide, the men feel compelled to investigate, eventually stumbling upon an evil force that perpetuates itself through tract housing.
Heisserer created a Web site last fall, www.dionaea-house.com, to build the mythology of the project. The site, which ended up getting millions of hits, was filled with fictional correspondence between the man and a friend who has since disappeared.
