Probably Jackie Chan's best film in the 1980s, and the one that put him on the map. The scale of this self-directed police drama is evident from the opening and closing scenes, during which a squatters' village and shopping mall are demolished. There are, clearly, differences between the original Chinese and dubbed English versions, with many of the jokes failing to make their way into the latter. The latter is also hampered by stars who sound nothing like their Chinese originals. In fact, the only thing the dubbing has corrected is the court trialat the time, trials in colonial Hong Kong were conducted in English, while the original has this scene in Cantonese!
Nonetheless, Chan's fighting style and the martial arts choreography inject humour where possible, so non-Cantonese audiences don't miss much. It's not, after all, the dialogue that makes a Chan flick, but the action and the painful out-takes. The story is easy to follow: Chan plays an incorruptible Hong Kong detective pursuing a gangland godfather (Cho Yeun), and assigned to protect a star witness (Brigitte Lin). The action is superb from beginning to end, and there's not much time to breathe in between. It'll never get you thinking, but what an entertaining, and well strung-together, film. Arguably, this is one of the best martial arts films out there.
