Demian Lichtenstein (Venus and Vegas) has signed on to direct a 3D action feature titled Relentless. Variety reports that the film will star Karl Urban (Eomer in LOTR: Two Towers and Return of the King, Ghost in Pathfinder) in a story about four extreme sports professionals who survive a plane crash in the Amazon. It turns out they have to use their extreme skills to escape an extremely dangerous situation where extremely homicidal natives hunt them. Hunt them extremely. God, this movie sounds?hmmm, what?s the word I?m looking for?
