Produced and directed by Johnnie To and Wai Ka Fai, the film stars Takeshi Kaneshiro and Gigi Leung. The story is based on the book A Chance of Sunshine by Jimmy Liao, who makes a cameo appearance in the film. It is also the first Chinese-language Asian film ever from Warner Bros. The original graphic novel is now sold under the name "Turn left, turn right" and consists of a series of detailed cartoon images, with a small amount of text in a diary style. The film has managed to include every single image in the book with a high level of accuracy, although some are fleeting. Leung plays a translator, and Kaneshiro plays a violinist who lives parallel lives and appears to be perfect for each other, but somehow fate seems to keep them apart. (Source: Wikipedia)
