The way Tarzan moved in the Disney film, sliding along tree trunks and the like, was based on the movement of skateboarders and snowboarders. Seeing as Tarzan had bare feet this method of movement is ludicrous.
Yes, but: the way Burroughs conceived of him traveling is the way monkeys and small apes travel. He could never have done it because, first, he was too heavy and would have broken a branch and fallen to his death in the first few jumps, and, second, that mode of travel depends on having gripping hands on all four limbs, as well as a prehensile tail. And of course, in the movies, there was always a handy vine that was connected to something only at the upper end so he could swing on it, but still wasn't dead and rotten from not having any roots at the ground end. So the Disney version is ludicrous, but no more so than the books or the prior movies - and visually more interesting.
I don't see anyone complaining about the aerial antics in Crouching Dragon, whatever, being ludicrous. Double standard?
