Police Story 4: First Strike (traditional Chinese: IV), released in English-speaking markets as Jackie Chan's First Strike, is a 1996 action-adventure film made in the typical humorous style of Jackie Chan.
Jackie reprises his role as Chan Ka-Kui (also known in some versions as Jackie) yet again as a Hong Kong cop who works with Interpol to track down and arrest an illegal weapons dealer. Later Jackie realizes that things are not as simple as they appear and soon find himself a pawn of an organisation posing as Russian intelligence.
The movie was shot partially in Brisbane in Queensland, Australia where the last half of the movie is based. Chinatown, Brisbane in Fortitude Valley and Underwater World on the Sunshine Coast were used. The movie was shot in the months between August and November 1996.
To advertise First Strike, Jackie recorded the song Zenmo Hui and also made music-video for it. As is typical with Chan's pictures, the US version does not feature the theme song.
