Derailed is a 2005 crime thriller film directed by Mikael Håfström and written by Stuart Beattie, based on the 2003 novel of the same name by James Siegel.

Starring Clive Owen, Jennifer Aniston, Vincent Cassel, Melissa George, Giancarlo Esposito, David Morrissey, RZA, and Xzibit, the film follows Charles Schine and Lucinda Harris who are having an extramarital affair and are assaulted and robbed by Philippe LaRoche in a hotel room.

Chicago advertising executive Charles Schine lives with his wife Deanna and their daughter Amy, who suffers from type 1 diabetes, which requires expensive medical treatment.

On a commuter train to work one morning, Charles meets a woman who tells him she is Lucinda Harris, a financial advisor who is married with a daughter.

Charles takes the money from the account meant for his daughter's medical treatment, goes to Lucinda's apartment, and makes the payoff to LaRoche and his partner Dexter.

He reaches her apartment, which is now being shown to new prospective renters, and discovers that Jane's photograph of her purported daughter is actually a cut-out of a stock picture from a brochure.

Charles knocks LaRoche unconscious outside the hotel room door, disarms him, and bursts in, telling a confused Sam the scheme he has been set up for.

[4] Roger Ebert of the Chicago Sun-Times awarded the film two and a half out of four stars and believed that Owen's and Aniston's performances were intriguing.

Ebert said, "Clive Owen was my candidate for James Bond, and can play hard and heartless rotters (see Closer), but here he is quiet and sad, with a sort of passivity.
