John Woo Yu-Sen SBS (Chinese: 吳宇森; born September 22, 1946) is a Hong Kong filmmaker, known as a highly-influential figure in the action film genre. He was a pioneer of heroic bloodshed films (a crime action film genre involving Chinese triads) and the gun fu genre in Hong Kong action cinema, before working in Hollywood films. He is known for his highly chaotic 'bullet ballet' action sequences, stylized imagery, Mexican standoffs, frequent use of slow motion and allusions to wuxia, film noir and Western cinema.
