10 More Horror Movies With Seriously Messed Up Endings

In terms of minimalist movies, Rodrigo Cortés' Buried is something of a modern-day masterpiece.

With 99% on the attention on Ryan Reynolds' Paul Conroy, Buried finds Reynolds' character trapped in a coffin buried underground in the middle of Iraq. A US truck driver stationed in the country, Paul and his colleagues are attacked. By the time Paul regains consciousness, he finds himself buried alive with only a select few items - such as a cell phone, lighter and knife - to hand.

The crux of this claustrophobia-inducing effort sees Paul using his BlackBerry to contact 911, the FBI, the State Department and have several back-and-forths with Dan Brenner of the Hostage Working Group.

Brenner eventually has details on where to find Paul's coffin, and audiences get a pulsating, tense final few minutes as a rescue team frantically dig while Brenner assures Paul via phone that he's going to be okay as sand piles into his casket.

In an utter gut punch of a finale, it's revealed how Brenner and his team had been led to the site of another buried coffin. From there, Paul's coffin is fully engulfed by sand as he suffocates to death.
