As I write this, WCEU, one of the local PBS affiliates is airing Touching the Void. From http://www.pbs.org/previews/touchingthevoid/:

In 1985, Joe Simpson and Simon Yates set out to climb the forbidding 21,000-foot Siula Grande in the Peruvian Andes - the only mountain in the Peruvian range that hadn’t yet been conquered. Young, fit and skilled, climbers Simpson and Yates were confident they would succeed. What happened on their trip has since become a mountaineering legend about human endurance and the will to survive. Based on Simpson’s international best-seller, the… film, which combines dramatic and documentary techniques, was shot on location in the Peruvian Andes….

I rented this when it came out on DVD. The film is at times breath-takingly beautiful because of its location and frequently spine-chillingly horrific because of the ordeal the climbers endured.
