My Lucky Stars is a 1985 Hong Kong action comedy film directed by Sammo Hung Kam-bo (洪金寶), written by Barry Wong Ping-yiu (黃炳耀), and starring Sammo, Jackie Chan (成龍) and Yuen Biao (元彪). It was released as 5 Lucky Stars in Japan and as Ninja Encounter in the Philippines. My Lucky Stars is the second film in the Lucky Stars series, and a semi-sequel to Winners and Sinners, with many of the same actors returning as the "Five Lucky Stars" troupe, albeit with different character names and slightly different roles.
Two Hong-Kong cops are sent to Tokyo to catch an ex-cop who stole a large amount of money in diamonds. After one is captured by the Ninja-gang protecting the rogue cop, the other one gets his old Orphanage gang, dubbed the "Five Lucky Stars," to help him. They don't like this much, but they do it.
