"Mamma Mia" star Amanda Seyfried has joined the cast of thriller "You Should Have Left".
The film, written and to be directed by David Koepp, also features actor Kevin Bacon and will be produced by Blumhouse Productions.
Koepp, an industry veteran, is best known for writing films such as "Mission: Impossible", "Jurassic Park", "Spider-Man", "War of the Worlds" and others.
The film, which is expected to start shooting later this year, follows the "unsettling story of a wealthy man with a younger wife and a 6-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."
