His Hollywood films include Hard Target, Broken Arrow, Face/Off, and Mission: Impossible 2.

He also created the comic book series Seven Brothers, published by Virgin Comics. In 2002, Dave Kehr in The Observer called Woo "possibly the most influential director making movies today." Woo names his three favorite films as David Lean's Lawrence of Arabia, Akira Kurosawa's Seven Samurai, and Jean-Pierre Melville's Le Samouraï.
