10 Movie Reveals That STOPPED You From Walking Out

10. Lucinda Is In On The Con - Derailed

Let's kick things off with the watchable yet mostly forgettable thriller Derailed, which centers around an advertising exec, Charles Schine (Clive Owen), who embarks on an extramarital affair with a similarly married woman, Lucinda Harris (Jennifer Aniston).

Charles is eventually blackmailed by a man named Philippe LaRoche (Vincent Cassel), who has kidnapped Lucinda and promises to kill her if he doesn't pay up $100,000, which Charles promptly does by taking the money from an account funding his daughter's medical treatment.

Pretty typical erotic thriller fare that doesn't merit much of your attention, right?

But at this point Charles heads to Lucinda's work and finds that she actually goes by the name Jane, before discovering that a picture of her daughter she showed to him was actually cut out from a brochure.

And then, the shoe finally drops - Charlie tracks Jane down and spots her kissing LaRoche, confirming that she was in on the con from the very beginning.

It's a twist that relies on the audience's overall perception of Jennifer Aniston - she very rarely plays villains, and is far from the most natural fit for a femme fatale.

As such, it comes as a genuine shock, all the more so as Jane is then shot and killed during a climactic gunfight between Charles and LaRoche.
