THE GAME CHANGERS(Louis Psihoyos, Canada/U.S.). 88 minutes. Rating:NNN

Louis Psihoyos follows elite athletes who have thrived on plant-based diets, overturning the argument that a vegetarian regimen will weaken you.

With UFC fighter James Wilks leading the way, the pic spotlights everyone from track-and-field star Carl Lewis to Arnold Schwarzenegger and beyond, making a strong case for saying no to meat.

But when the pic turns to science it gets confusing. A segment on the meat industry’s marketing techniques is too long – just compare it to tobacco strategies and be done with it. And the film’s appeal to vanity and men’s virility is problematic. Better to concentrate more on how plant-based diets could save the planet.

Correction: April 24, 2018 An earlier version of this review incorrectly stated the strongest man in the doc was shown eating cheese derived from milk. He was eating a plant-based cheese.We regret the error.
