Nicky - obsessive24 - has created a very fast and violent video using Ong Bak fight scenes to Breathe by the Prodigy. The video is very exciting, balletic and brutal. Bang bang smash. You can view or download it here.
ETA - I think the action, particularly because bodies do impact hard in these fight scenes, makes you imagine the weight, no the mass, the mass and the momentum of the bodies. You can only make sense of the fights if you mentally model the heaviness and strength of the body in motion, so it is quite sexy.
