All's Well, Ends Well (1992)

If you watch one Lunar New Year comedy, make it this one. Clifton Ko puts Leslie Cheung, Stephen Chow, Maggie Cheung, Sandra Ng, Teresa Mo and Raymond Wong into one story about three hapless brothers and their romances, and every scene trades on audiences knowing exactly who these stars were. Leslie Cheung as an effeminate flower arranger caught in a gender-bending battle of the sexes is a joke about his own image that he clearly enjoys, while Chow's womanizing DJ and Maggie Cheung's movie-mad girlfriend stage parodies from Pretty Woman to Ghost. A huge hit that spawned a long run of sequels.
