the box (2009)

"So who is Mr. Stewart?"
A family (Cameron Diaz, James Marsden, & Sam Oz Stone) are given a button, and a choice, by Arlington Stewart (Frank Langella). Press the button and someone they do not know will die, and in return they will receive one million dollars. They have 24 hours to decide... A good psychological thriller is squandered when the film descends into a confusing mess half way through.
