In the marketing for the movie King Lines they say:
(2007) The best-selling climbing film of all time. Follow Chris Sharma on his ultimate global quest to redefine the possible in the vertical world.
Clearly movies like Cliffhanger aren't included in this statistic. That being said, was that actually true at one time or is that subtly qualified hype aka best-selling for this studio? For it to be anything but hype there would have to be some organization that tracks the sales of all climbing movies from the various producers. If that organization exists would I be able to figure out the best selling skiing, diving, also from them?
