I saw a shortened version of this last night at the Banff Film Festival. You crazy kayakers will probably like this, big water that scares this crew must be freaking HUGE. Video always makes water look smaller, even boring, but not this stuff. Check out the zambezi footage and then the white nile, both at high water, rain runoff. I don't think they show either of those sections on this teaser. Too bad it's just a teaser, but probably worth buying as all proceeds go to the Sun Catchers Project, something amazing alone and worth watching this teaser for.
