You might not be tempted by Buried – after all, it’s by a director you’ve never heard of and it stars an actor best known for playing vapid romantic interests or unnecessarily violent supervillains. We’d more or less written Ryan Reynolds off too, but in this extraordinary film he demonstrates a range and talent which left us gasping for breath. A bit like him, because he’s been buried alive.

Paul Greengrass’s Green Zone centres on one of the fundamental questions surrounding the Iraq war – when American and British forces withdraw completely from Iraq will the lasting legacy be peace and democracy? Or will it will be a deep-rooted suspicion that the infamous weapons of mass destruction, the supposed justification for the invasion, never existed? It’s an interesting question, though the answers in this film are perhaps just a little too easy.

It was only a matter of time before we started to hear of the hot picks at this year’s Sundance Film Festival, and it appears that Roderigo Cortez’s film Buried is amongst the first to cause a stir.
