I just watched this mountain bike video and it's insane... It's like the Art Of Flight mixed with Further (Jeremy Jones), but on mountain bikes. These guys travel the globe and get heli's to drop them off on top of mountains where they ride insane chutes and lines... crazy! I would be impressed to see guys do these lines on snow, let alone rock and dirt. Totally worth watching the movie.
Here's a trailer for it, but it just doesn't do it justice at all... the trailer is kind of dull until the 2 minute mark, and check out the line at 3:50... awesome.
