Meanwhile, Sam left the Shaw Bros. Company to work with Golden Harvest, where Bruce Lee, very fond of his songs, taught him some martial art moves. Sam did a few action films for Golden Harvest. Michael joined him at the Golden Harvest and they were immediately successful with the Game Gambler Play (1974), a comedy about HK people number one hobby, i.e. gambling. This was written and directed by Michael. They carried on with The Last Message released in 1975. It's a comedy taking place in a mental hospital, where Michael and Sam always try to perform the best con.
Sam and Michael's first movies made huge hits because they integrated a social satire to Cantonese sense of humour, a novelty in the local cinema. They allowed then the Golden Harvest to stand up after the lost of Bruce Lee. It's worth noting that these successes have contributed to rehabilitate films in Cantonese language and to outdo movies in Mandarin language. But if Game Gambler Play and The Last Message grossed a lot of money in HK, the sense of humour displayed was mainly verbal and very much full of Cantonese jokes. Full of typical HK features, these first films worked for locals. But the Hui Bros. had to find a way to conquer South East Asian markets.
