The Disney movie Up was inspired by Angel Falls in Venezuela's Canaima National Park. Not surprising really, considering it's the highest waterfall in the world. The Churum river teeters over the top and free-falls for a gut-wrenching 979 metres. You might think head-in-the-clouds height gave this magnificent waterfall its name, but it was actually named after pioneering pilot, Jimmy Angel, who's famous for making an emergency landing on the top of Angel Falls in 1937. Fast forward 70 or so years and Disney has Carl Fredrickson replicate the daring feat in Up. But, as every kid knows, it's his house he lands at the top of the waterfall.
