What if someone gave you a box containing a button that, if pushed, would bring you a million dollars...but simultaneously take the life of someone you don't know? Would you do it? And what would be the consequences?

The year is 1976. Norma Lewis (CAMERON DIAZ) is a teacher at a private high school and her husband, Arthur (JAMES MARSDEN), is an engineer working at NASA. They are, by all accounts, an average couple living a normal life in the suburbs with their young son...until a mysterious man with a horribly disfigured face appears on their doorstep (FRANK LANGELLA) and presents them with a life-altering proposition: the box.

With only 24 hours to make their choice, Norma and Arthur face a momentous moral dilemma. They soon discover that the ramifications of this decision are beyond their control and extend far beyond their own fortune and fate.

"The Box" is based upon the classic short story "Button, Button" by Richard Matheson. It was written for the screen and directed by Richard Kelly, whose 2001 sci-fi mystery thriller "Donnie Darko," a cult classic, earned a Grand Jury Prize nomination at the Sundance Film Festival. "Donnie Darko" went on to screen at film festivals around the world and brought Kelly Independent Spirit Award nominations for Best First Feature and Best First Screenplay.

"The Box" stars Cameron Diaz ("The Holiday"), James Marsden ("X-Men: The Last Stand"), Oscar® nominee Frank Langella ("Frost/Nixon"), James Rebhorn ("The International") and Holmes Osborne (television's "Invasion.")

It was produced by Sean McKittrick, Richard Kelly and Dan Lin, with Sue Baden-Powell, Ted Field, Paris Kasidokostas Latsis, Terry Dougas and Edward H. Hamm Jr. serving as executive producers. The behind-the-scenes creative team includes director of photography Steven Poster ("Stuart Little 2"), production designer Alexander Hammond ("Flightplan"), editor Sam Bauer ("Donnie Darko") and costume designer April Ferry ("Terminator 3: Rise of the Machines"). Original music is provided by Win Butler, Regine Chassagne and Owen Pallett.

Warner Bros. Pictures presents, in association with Radar Pictures and Media Rights Capital, "The Box." The film will be distributed domestically by Warner Bros. Pictures, a Warner Bros. Entertainment Company.
