Jake Gyllenhaal wants to show off his wild side. The actor teams up with adventure and survival expert Bear Grylls for an upcoming episode of 'Man vs. Wild.'

According to The Discovery Channel, the duo heads to Iceland together for the season premiere of the hit survival show, where they find themselves surrounded by active volcanoes and massive glaciers in the hard Icelandic landscape.

So why did the Academy Award-nominated actor decide to make the trip with Grylls?

"For me, it's all about discovery," Gyllenhaal said of the experience, while Grylls added that the actor held his own during the trek.
