The film version varies from that of the book, which is akin to Stephen King’s The Shining. You Should Have Left is the unsettling story of a wealthy man with a younger wife and six-year-old child.  Mistrust and suspicion characterize their marriage while they are in a remote location that may or may not be obeying all the physical laws of the universe.Bacon brought the source material to Koepp who directed the actor in 1999’s Stir of Echoes. Blumhouse acquired the project, following Koepp and Bacon’s pick up of the book’s film rights.
