Wong Kar-wai is a Hong Kong filmmaker and most of his movies are beautiful romances. He makes movies about flashing city lights and Cantonese people smoking cigarettes and somehow makes you feel like romance is the only thing in the whole world. My favorite of his is Chungking Express (1994) about two policemen in Hong Kong with parallel romances: one with a mysterious criminal, the other with a mysterious waitress.
Another great one, and his most widely acclaimed film, is In The Mood For Love (2000) about two neighbors in 1960s Hong Kong who suspect that their spouses are cheating on them with each other’s spouse, so they set out to explore how this romance could’ve began, and come to fall in love themselves.
Another one that is more dark and seedy is Fallen Angels (1995) where a hitman tries to escape his career and navigate his relationship with his underworld employer who is secretly in love with him.
