The best Michael Dinga’s action movies

Star Chow (Stephen Chow) is an officer in the Royal Hong Kong Police's elite Special Duties Unit (SDU). During a meeting with his senior officer, Inspector Yip (Deanie Ip), Star jokingly suggests he wishes to be reassigned to the traffic unit. Star immediately finds himself demoted to Constable engaging in traffic duty on the streets of Hong Kong. After being made the scapegoat for a failed high school terrorist investigation, Star hastily resigns from the police. He decides to enroll at the high school to launch his own private investigation. But Star realises the investigation won't be easy when he discovers that the bumbling, incompetent CID detective Tat (Ng Man Tat) is also undercover at the high school.

A cop who loses his partner in a shoot-out with gun smugglers goes on a mission to catch them. In order to get closer to the leaders of the ring he joins forces with an undercover cop who's working as a gangster hitman. They use all means of excessive force to find them.

Two cops--both best friends and partners--both become the subject of a beautiful news reporter's documentary. The two soon find themselves competing for screen time as well as the love of the reporter while after a murderous arms dealer.

Earnest cop James (Cheung Kwok-leung) works for the Commercial Crime Bureau and is keeping a sharp eye on slick business man Lee Siu-pong (Wong Kam-kong). When his business endeavours garner the attention of an enterprising extortionist, Lee has the blackmailer killed. Fearing that the incriminating document has fallen into the hands of James, Lee does the only thing that a red-blooded criminal might -- he kidnaps the cop's girlfriend Suki (Sharla Cheung Man). When James gives chase, he finds himself horribly burned in an explosion detonated by Lee. After months of painful recovery, James dons a silver mask and sets out for bloody, gut-wrenching vengeance. Meanwhile, Suki, who has become Lee's unwilling mistress, plots for the thug's gory demise as well.
