It sounds like just one more testosterone-fuelled war epic with a storyline of patriotism, designed to make a grateful Pentagon beam. But don't look for Tom Cruise or Daniel Craig on the promotional posters because in Act of Valor, which opens in the United States this weekend, the actors playing soldiers won't be actors at all.
However the film is received by the critics - acting skills will not get top mention - Act of Valor will be remembered for shredding a decades-old understanding about the making of war movies: that while directors are rarely averse to getting into bed with the US military there has always been at least a small bolster between them, for decency.
Made for US$12 million ($14 million) by first-time directors Mike McCoy and Scott Waugh, the film follows a mission by a band of Navy Seals involving the rescue of a CIA agent from a Central American drugs gang, that in turn exposes a terror plot against the US hatched by a group of radical Chechens.
The story-telling mixes documentary with fiction, but entirely real are the protagonists. They are all active-service Navy Seals.
Hollywood does have a long history of making films examining the dark side of war, going back even to the 1930 epic All Quiet on the Western Front, a tale of German conscripts in the trenches, Dr Strangelove, M*A*S*H and Apocalypse Now, which respectively offered contrarian takes on the Cold War, the Korean War and the Vietnam conflict.
