Hong Kong action cinema is the principal source of the Hong Kong film industry's global fame. Action films from Hong Kong have roots in Chinese and Hong Kong cultures including Chinese opera, storytelling and aesthetic traditions, which Hong Kong filmmakers combined with elements from Hollywood and Japanese cinema along with new action choreography and filmmaking techniques, to create a culturally distinctive form that went on to have wide transcultural appeal. In turn, Hollywood action films have been heavily influenced by Hong Kong genre conventions, from the 1970s onwards.
The first Hong Kong action films favoured the wuxia style, emphasizing mysticism and swordplay, but this trend was politically suppressed in the 1930s and replaced by kung fu films that depicted more down-to-earth unarmed martial arts, often featuring folk heroes such as Wong Fei Hung. Post-war cultural upheavals led to a second wave of wuxia films with highly acrobatic violence, followed by the emergence of the grittier kung fu films for which the Shaw Brothers studio became best known.
Hong Kong action cinema peaked from the 1970s to the 1990s. The 1970s saw a resurgence in kung fu films during the rise and sudden death of Bruce Lee. He was succeeded in the 1980s by Jackie Chan—who popularized the use of comedy, dangerous stunts, and modern urban settings in action films—and Jet Li, whose authentic wushu skills appealed to both eastern and western audiences. The innovative work of directors and producers like Tsui Hark and John Woo introduced further variety, with genres such as heroic bloodshed and gun fu films, and themes such as triads and the supernatural. However, an exodus by many leading figures to Hollywood in the 1990s coincided with a downturn in the industry.
