In 2008, photographer and filmmaker Tim Hetherington lived with an American platoon in the Korengal Valley of Afghanistan, one of the nation’s most dangerous outposts. Since then, he’s released a series of photographs called Sleeping Soldiers, an experimental audiovisual project of the same name, and a full-length documentary produced with author Sebastian Jung called Restrepo, which won the 2010 Sundance Grand Jury Prize. Restrepo is slated for a summer 2010 theatrical release.
