Days of Being Wild is the first of Wong Kar-Wai’s films to feature the aesthetics and themes that continue to define his filmmaking. The first collaboration between Wong and cinematographer Christopher Doyle, the film bears Wong's distinct visual style, and begins to explore the questions of friendship, sensuality, and longing that are subjects for his later films. Set in 1960 Hong Kong, Wong uses flashbacks and flashforwards to play with the concepts of chronology and memory, and the film uses Wong’s favorite actors Leslie Cheung (as ladies’ man Yuddy), Maggie Cheung (as a shy concessions worker) and Tony Leung (in a brief appearance).
