Jake Gyllenhaaldoesn't sound too convinced of his own convictions when he decides to hang by a rope above a huge gorge in the middle of inclement weather, but hey, he goes through with it!
For an A-list movie star, Gyllenhaal makes for a pretty good rugged outdoorsman/ adventurer as he joins Bear Grylls for the season premiere of Discovery's "Man vs. Wild." The death-defying Prince of Persia himself would be impressed as Jake takes on Iceland’s mountains, huge glaciers and active volcanoes.
Let fear be your guide as you watch the clips below, courtesy of The Hollywood Reporter. You can watch Jake's episode of "Man vs. Wild" on Monday, July 11 at 9 p.m. on Discovery.
