A clip from an upcoming episode of Man vs. Wild, featuring actor Jake Gyllenhaal and reality TV tough guy Bear Grylls in Iceland, has been released.
Gyllenhaal visited Iceland last April, although initially no one knew the exact reasons for his arrival. It was later revealed that he, along with Bear Grylls, travelled up to Eyjafjallajökull and Fimmvörðuháls to battle the elements and record the adventure for the Discovery Channel show Man vs. Wild.
The episode airs 11 July on the Discovery Channel and Channel 4 in the UK. A clip from the episode can be seen below:
