Longtime friends Jackie Chan, Sammo Hung, and Yuen Biao—who had worked together since childhood as part of a Beijing opera troupe—join forces for this rollicking blend of action thrills and lunatic humor, which sees Chan’s undercover agent recruiting his band of outlaw buddies to travel to Japan in order to help him catch a rogue cop who has stolen millions in jewels. Though not the main star, Chan lights up the screen in the film’s most exhilarating set pieces: a kinetic amusement-park-set opening and a surreal haunted-house finale, both stylishly and creatively staged by director-star Hung.
