The Game Changers is a new documentary about the vegan movement within sports and physically demanding occupations. It's by Louie Psihoyos (director of The Cove) and executive produced by James Cameron.

Directed by Louie Psihoyos and executive produced by James Cameron, The Game Changers tells the story of James Wilks — elite special forces trainer and winner of The Ultimate Fighter — as he travels the world on a quest for the truth behind the world's most dangerous myth: that meat is necessary for protein, strength and optimal health. Meeting elite athletes, special ops soldiers, visionary scientists, cultural icons, and everyday heroes, what James discovers permanently changes his relationship with food and his definition of true strength.

For the curious, Jeremy Lapro just shared his vegan diet over at Bodybuilding magazine.

And here's a nice interview with vegan bodybuilder Nimai Delgado, showing that offline, the debate within bodybuilding is not as maniacal as it is on some of the forums:
