On the season premiere of 'Man vs. Wild,' actor Jake Gyllenhaal took on a very different role: human popsicle.

In order to stay dry while crossing a frigid river in Iceland, Gyllenhaal and Bear Grylls stripped off a portion of their clothing in sub-zero temperatures.

"I joined up for this, right?" asked Gyllenhaal, while removing his shirt.

Then, the two slowly crossed the river and emerged on the other side. Grylls was stoic and didn't seem bothered by the cold, but Gyllenhaal was clearly freezing, and struggled just to put his clothes back on.
