Running Wild with Bear Grylls S04E04 - Don Cheadle

Dropped from a helicopter into unyielding terrain, Don and Bear get creative with a deer antler to cross a raging river, rappel a massive cliff, and attempt a commando-worthy climb to the top of a towering railroad bridge. But the discovery of a rotting porcupine carcass, which Bear eyes for dinner, will raise Don's pulse like nothing else. Along the way, Don details his family-oriented home life, the ups and downs of a legendary career, and the secretive workings of a Marvel movie set.
