Copying and pasting from the film's website:
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.
Louie Psihoyos won an Oscar for The Cove. "The world's most dangerous myth" is a bold premise for a documentary. Given the fierce debates we've had on Cake about heart disease, Alzheimer's and athletic performance versus diet, I'm super anxious to see what the film has to say.
