Once a Cop (Chinese: ????) is a 1993 Hong Kong action film directed by Stanley Tong and starring Michelle Yeoh. It is a spin-off of Jackie Chan's Police Story film series involving the character Yeoh portrayed in Police Story 3: Super Cop. The film is also known as Project S in original territories and many other titles, including Police Story IV (inaccurately), Police Story 3 Part 2, Supercop (UK) and Supercop 2 (US). It is confirmed Dragon Dynasty will re-release the movie as Supercop 2 after they re-release the first Supercop in January. Although Jackie Chan only has a cameo appearance in this film, some DVD covers prominently featured Chan, misleading audience to think that he was one of the main characters. In Hong Kong, the film only managed to gross HKD$9,337,853(as of 8 November 1993). The film was released to the US nearly three years later and it managed to gross US$16,270,600.
