Following up on his two-fisted 2000 flick The Mission, Johnnie To, along with Wai Ka Fai, directs this high-octane shoot 'em up about a pair of hired killers vying for their reputation and for a beautiful girl. O (Takashi Sorimachi) is a reclusive, highly disciplined assassin who is considered the top killer of Hong Kong. Since the murder of his comely housekeeper, with whom he secretly has fallen in love, he has grown even more inward. For him, any connection to the outside is fraught with danger, usually leading to death. Tok (played by pop star and heartthrob Andy Lau) is the polar opposite of O -- brash and eager to be number one. Chin (Kelly Lin) is O's part-time housekeeper -- a replacement to her murdered predecessor -- and current obsession. When Tok seduces her -- in between knocking off gangsters in a Bill Clinton mask -- he forces O out of his seclusion and into a confrontation with his rival. Meanwhile, Interpol, lead by Inspector Lee (Simon Yam of Bullet in the Head fame), is hot on their trail. This film was screened at the 2001 Toronto Film Festival.
