In the Mood for Love (2000)

Sight and Sound's 2022 critics' poll placed it fifth among the greatest films ever made, higher than anything else from its decade, and it earns that by leaving almost everything unsaid. In 1962 Hong Kong, two neighbours discover that their spouses are having an affair with each other. Tony Leung became the first Hong Kong actor to win Best Actor at Cannes for it, Maggie Cheung moves through narrow corridors in one high-collared cheongsam after another, and a waltz borrowed from a Seijun Suzuki film turns each trip to the noodle stall into a ritual. If you see one film from 2000, make it this.
