From NetFlix:

While on a job in Iraq, civilian contractor Paul Conroy (Ryan Reynolds) is attacked and kidnapped, then awakens to find himself buried alive in the middle of the desert with nothing but a lighter, a candle, a cell phone and a knife. Does Paul have the instincts he’ll need to save himself? Director Rodrigo Cortés crafts a tense psychological thriller with sociopolitical undertones that doubles as an exercise in claustrophobic terror.

If you are claustrophobic, DO NOT WATCH THIS FILM !

If you read the Wikipedia article you will find rave reviews such as “Wringing a seemingly impossible amount of gripping drama out of its claustrophobic premise, Buried is a nerve-wracking showcase for Ryan Reynolds’ talent.” Here is a film in which Ryan Reynolds is anything but a handsome Hollywood star.

Incredibly spell-binding , I could not take my eyes off the screen. But this is a film with a nasty message. We are asked to believe that Paul Conroy was purposely setup by his American contractor. At the very least his company CRT weasels out of its responsibilities by concocting a reason for claiming that he was discharged from the company JUST BEFORE being kidnapped. How on earth could we know that such things have ever occurred ?

From a technical standpoint: would not Paul have exhausted the air in the buried crate a lot sooner than the film shows ?

In no way can I spoil this film for you. You will just have to suffer through the torture to see what happens.
