My Lucky Stars is one of Sammo Hung's production featuring the three dragons - Sammo, Jackie, and Biao. Jackie Chan had near cult following in Japan by the time this movie was made. The movie took advantage of location shooting in Japan to appeal to its audiences, and add a touch of international flavor. His popularity must have sparked other projects that were done with collaboration between Hong Kong and the Japanese movie industries. For instance, the amusement park used for location shooting is the same amusement park (Fujikyu Highland) used for the shooting of Peacock King that also starred Yuen Biao.
Muscles (Jackie Chan) and Ricky (Biao Yuen) are under cover HK cops working in Japan to capture one of their colleagues who've gone bad. They are faced with ninjas at the amusement park that prevents them from capturing the cop. Fastbuck (Sammo Hung) is a convict, but he's recruited also to bring back the cop who stole $100M.
This movie stars almost the same cast as Winners and Sinners that was also produced by Sammo. The atmosphere of the story is almost identical too. Both featuring Sammo as an ex- con. They are so similar that it's hard to tell which movie is which at some point. The story goes nowhere until the last where there's massive amounts of hand to hand combat. This is also same as the Winners and Sinners. The story is made around the talents of these five stars, and isn't particularly fresh approach compared to other HK movies of that time. Similar action has already been seen on other Jackie Chan movies.
Average HK movie that's mostly comedy, and some good actions sprinkled in between.
