Restrepo will go head-to-head with Banksy's documentary Exit Through the Gift Shop at the 83rd Academy Awards on 27 February. Other nominees in the best documentary feature category include Waste Land, Inside Job and Gasland.

In Restrepo, "the lives of soldiers at war are chronicled in an exploration of the experiences of the 173rd Airborne Brigade in Afghanistan's Korengal Valley," according to the Academy Awards nominators. "Through conversations with the men over a period of many months, a portrait emerges of the devastating toll that war takes as lives are lost and those who survive struggle to find meaning in their devotion to their comrades."

Hetherington and Junger filmed Restrepo while on assignment in Afghanistan for Vanity Fair. The film has already won the Grand Jury Prize at last year's Sundance Film Festival.

Hetherington, a British photojournalist, has won the 2007 World Press Photo for an image shot in the same Korengal Valley where Restrepo takes place. He returned in 2007 and 2008, with Junger to finish his assignment and shoot the documentary.
