For his latest role, Bradley Cooper leapt onto a hovering helicopter, rappelled down a 400-foot cliff and pulled himself across a 100-foot ravine in one of the harshest climates in North America.
For his latest role, Bradley Cooper leapt onto a hovering helicopter, rappelled down a 400-foot cliff and pulled himself across a 100-foot ravine in one of the harshest climates in North America. His reward wasn’t an Oscar nomination or a big box office hit. It was a hug from adventurist Bear Grylls and some words of encouragement. Cooper is one of several high-profile celebrities putting their survival skills to the test in Season 8 of Nat Geo’s “Running Wild with Bear Grylls: The Challenge.” Grylls told the AP the best guests are always those who come with a willingness to go with it over looking good.
