In reply to Jim233:
Can I just say - it's well worth seeing (having attended the screening in Bristol last night), so book a ticket. Grabbing the DVD or watching on demand is one thing, but it'll never equal seeing El Cap on a cinema screen. It goes without saying that the efforts of Caldwell/Jorgeson are extraordinary, but props are also due to the filmmakers; I'm not sure how many of us would fancy hanging about, dangling in space at 2000-odd feet, in all weathers, day and night, over several years to capture the climbing.
