Some people are inclined to risk their lives, climbing towering mountains and walls in unknown places. They are mountaineers who go out of their way, seeking more challenging paths such as Reinhold Messner, Conrad Anker, David Lama, Tommy Caldwell, Adam Ondra and Lynn Hill. The extensive selection of the best existing climbers itself makes this documentary more than worth watching. It isn’t just a typical collection of Q&As from legendary mountaineers, but truthful accounts from the heart. It is moving to hear their testimonies about how they have learned to live through climbing. (Billy CHOI)
