Directed by Mathieu Kassovitz (La Haine (1995), The Crimson Rivers (2000) and Babylon A.D. (2008), produced by Joel Silver and Robert Zemeckis and written by Sebastian Gutierrez (Snakes on a Plane (2006)), this dark horror film has some good ideas, but it's let down by pedestrian plotting and derivative scares, despite the best efforts of the cast, who are wasted in this supernatural thriller. Psychiatrist Dr. Miranda Grey (Halle Berry) works at a mental hospital, and while driving home one night, is possessed by a ghost. When she wakes up, she's restrained in the mental hospital where she works, and is told by Dr. Pete Graham (Robert Downey, Jr.) that she murdered her husband Douglas (Charles S. Dutton). Miranda can't believe this accusation, as she can't remember it. She's forced to conform to hospital life, which means bonding with her former patient Chloe Sava (PenÚlope Cruz). But, one night, Miranda witnesses something happening to Chloe, which could explain as to why she's been banged up. Director Kassovitz seems to have had bad luck while working in Hollywood, maybe this and Babylon A.D. should convince him to stay away. It has shades of Samuel Fuller's Shock Corridor (1964), and this is a film which should have been made 40 years previously, as it might have been better.
