Kung Fu Hustle (Stephen Chow, 2004)
It used to be possible to split martial arts films roughly into two broad categories: those that featured largely unassisted physical feats, such as the films of Jackie Chan; and those reliant on more over-the-top, heavily faked wire-work, such as Once Upon a Time in China or Crouching Tiger, Hidden Dragon. The last few years, however, have seen the emergence of a variant of the latter: computer assisted martial arts, as seen prominently in the fight with many Agent Smiths in The Matrix Reloaded. Here the computer fakery moves beyond just the digital removal of wires, and starts creating digital stunt men and props. Once a fight is at least partially animated inside a computer, anything is possible. In unassisted martial arts, a kick might knock someone over. With wire-work, it might send them flying across a room. With digital martial arts, however, it can send them over the horizon.
