Getting dropped off in the middle of Utah might not sound too dangerous ... just find a highway and hitchhike your way back to Salt Lake City, right? Not so fast. As Bear Grylls found out on 'Man vs. Wild' (Fridays, 9PM on Discovery), Utah's rough outdoor terrain can be a unforgiving and dangerous.

Crossing rapids is dangerous business, no matter where the water is. Grylls had to apply his survival skills get by, tying a rope to a tree before entering the water. "I'm holding myself out of the main stream for as long as possible," he said in the voice-over. "Because when the full force of the water catches me, I'm gone."

You first heard about it a few weeks ago, but now you finally get to see Jake Gyllenhaal take his shirt off on 'Man vs. Wild' (Mon., 9PM ET on Discovery). Well, there was more to it than that.

He and Bear Grylls both shed their shirts in sub-freezing temperatures to keep them as dry as possible while they crossed a river. It's a far cry from a shirtless Gyllenhaal in the deserts of 'Prince of Persia.'

"I joined up for this, right?" Gyllenhaal lamented as he stripped. They made the crossing fairly quickly, making us cold just from watching them in the freezing water with the cameraman trying to keep the lens free of snow and ice.

Jake Gyllenhaal is getting in touch with his wild side.

On July 11, the Oscar nominee will appear alongside Bear Grylls on the Discovery Channel series 'Man Vs. Wild' with Bear Grylls.

Gyllenhaal and Grylls will trek through the Icelandic landscape -- through mountains, glaciers and volcanoes -- with the actor forced to shadow the host as they endure rough weather conditions. Their adventure will kick off six all-new episodes of the series.

Discovery Channel unveiled its lineup for the 2010-11 season this week, and it looks like more stellar programming for the real-life stories network. You can read more about it here, but two that caught my eye are 'Engineering the Impossible,' where a team of specialists search for clues about how some of the world's most fantastic structures were built; and 'The Rising: Rebuilding Ground Zero.' a documentary executive produced by Steven Spielberg.

This made me think about some of my favorite shows on the Discovery Channel, and I realized that they usually involve people in ridiculously disgusting or deadly situations. I think of these as the "real" reality shows, rather than the manufactured reality shows like 'Survivor' and 'The Amazing Race.'

Ok, we'll take Bear Grylls out of the equation, because, clearly, there's no need for him to be dropped into the wilderness and have to drink his own pee. But the others on my list are just awesome people doing death-wish jobs no one else wants to do. Follow me after the jump to see who made my top five list.

The 'Man vs. Wild' host's career just got a little wilder.

Discovery announced that Bear Grylls will host six episode of a new survival show called 'Worst Case Scenario,' based on the popular line of books published by Quirk Books.

The show will put Grylls in a series of heightened and dangerous situations to teach viewers how to survive them or at least walk away with most of your limbs still intact.

This isn't the first time the book series has gotten the TV treatment. TBS turned the book series into a reality information show that only lasted two seasons and featured a fresh-faced Mike Rowe before he found infamy as the host of Discovery's 'Dirty Jobs'.

Forget 'Man vs. Wild.' Survivalist Bear Grylls is turning his attention from the wild outdoors to the concrete jungle with Discovery's newest series, 'Worst Case Scenario,' The Live Feed reports.

Grylls, who gained fame teaching viewers how to use outdoor survival techniques in 'Wild,' will now be applying his know-how to life-threatening situations that could occur in our everyday lives, showing audiences how to handle urban disasters such as escaping a sinking car or surviving inside a falling elevator.

The series will be based on the bestselling book series of the same name, with six episodes ordered for a spring premiere.
