John Woo has contributed considerably to the immense popularity of Hong Kong action films. His best movies are characterized by unrelenting violence and overblown melodramatics. He is regarded as the legatee of Sam Peckinpah, who was the first to stylize violence, revealing it as an aesthetic ballet of human motion. In some of Woo's films there is at least one scene of people dancing.
Incidentally, one of Woo's first films, HAND OF DEATH, starred Jackie Chan, another Asian superstar who was to achieve fame abroad. Woo's best films were made back in Hong Kong. THE KILLER, made in 1989, is considered an action classic. He moved to Hollywood in 1993; he has worked there ever since making HARD TARGET. FACE/OFF, starring John Travolta and Nicholas Cage, is the director's best Hollywood production to date.
Woo's first film productions only had him sitting at the helm, without having a word in the script. Later, he would write or cowrite his films, all of which have become genre classics (from A BETTER TOMORROW onwards). In Hollywood, Woo also merely directs. A logical step would be to cowrite the scripts to his movies, which would, in turn, perhaps raise his standard again.
