In the Mood for Love (Chinese: 花樣年華; Chinese: Prime; lit. 'Flower-like period', 'the best years of one's youth') is a 2000 romantic drama film written, directed and produced by Wong Kar-wai. A co-production between Hong Kong and France, it portrays a man (Tony Leung) and a woman (Maggie Cheung) in 1962 whose spouses have an affair together and who slowly develop feelings for each other. It forms the second part of an informal trilogy, starting with Days of Being Wild and concluding with 2046.

The film premiered at the Cannes Film Festival on 20 May 2000, to critical acclaim and a nomination for the Palme d'Or; Leung won Best Actor (the first Hong Kong actor to win the award). It was selected as the Hong Kong entry for the Best Foreign Language Film at the 73rd Academy Awards, but it was not nominated. It is often listed as one of the greatest films of all time and one of the major works of Asian cinema.
