Bear Grylls is leaving Discovery Channel after six years on the air. According to an exclusive story by The Hollywood Reporter, Grylls and Discovery could not agree on appearances in two other unnamed projects.

Grylls' show, Man vs. Wild, premiered in 2006 and has been a hit ever since. Celebrity cameos included Jake Gyllenhaal, Will Ferrell and Ben Stiller. Grylls' online fandom grew when he began to eat and drink from natural sources - the most extreme being liquid squeezed from elephant dung and infamously drinking his own urine.

The show also created a debate on the new "survival real...

Survival expert Bear Grylls' son proved he's following in the TV adventurer's footsteps after rescuing a friend who fell into a river.

The Man Vs. Wild star's seven-year-old son Jesse managed to pull the little girl out of the water and drag her to safety.

Grylls explains, "They (the children) were in a little base in a stream and she fell in. And - I wasn't there, you know, and the story grows and grows every time he tells me - but he did rescue her and he was proud as punch to have dragged her out."

However, Grylls, who is also dad to sons Marmaduke, five, and four-year-old Hucklebe...

"No more time thinking. It's time to do it."

Jake Gyllenhaal doesn'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.
