Career: Chan had small roles in Bruce Lee movies Fist of Fury and Enter the Dragon, and also did stunt work and directed projects. After Lee died, Chan decided he didn't want to imitate him, so he developed his own film-making style, a mixture of action and comedy inspired by Buster Keaton and Harold Lloyd. By the 1980s, he was Asia's biggest star, and tried to break the US market by appearing in The Cannonball Run and its sequel. These days, Chan is a global superstar thanks to such movies as Rush Hour and Shanghai Knights and their sequels, and The Forbidden Kingdom, Kung Fu Panda, The Spy Next Door and the remake of The Karate Kid. In 2012 Chan announced he would be cutting down on the number of stunts he would perform in an attempt to take better care of himself.
