Jake Gyllenhaal went all out for his upcoming “Man vs. Wild” appearance with Bear Grylls -- and in a just-released clip from the show, we see him crossing a deep ravine on a rope ... in a snow storm!
Jake and Bear traveled to Iceland for the show's season premiere, where they tackle mountains, volcanoes and glaciers.
Of the experience, Grylls said in a press release "The wild is always very revealing - not only physically but mentally. You've got to smile when it's driving horizontal hail and be able to face your fears and just get on and do it -- and on both of those accounts, Jake came up strong."
Check out the sneak peek above. The season premiere airs July 11 on Discovery.
