Jackie Chan’s second directorial effort was also a film of important firsts: his first for upstart studio Golden Harvest and his first with cowriter Edward Tang, who would become a key collaborator. The star-filmmaker shows his increasing confidence with this endlessly inventive tale of a martial-arts student (Chan) who goes in search of his exiled brother, only to become entangled in a case of mistaken identity—with much amusement provided by Chan’s interplay with his real-life former schoolmate Yuen Biao. The epic finale, in which Chan goes from human punching bag to raging bull, is a bruising highlight of his career.
