Stephen Tung directed the Hong Kong action thriller Hitman in 1998. Jet Li, Eric Tsang, Simon Yam, and Gigi Leung feature in the film. On April 3, 1998, the picture was released.
Hitman begins with a flashback to the "King of Killers," a terrifying assassin who has been active throughout Southeast Asia. The King of Killers has no known collaborators or associates, is unaffiliated with any government, religious, or criminal organization, and their true identity has remained a mystery to this day. The King of Killers is suspected of being responsible for six killings in the last year alone, all of which have one thing in common: the victims were all criminals who deserved to die. The film then rapidly shifts to the King of Killers' most recent assassination, a well-publicized assassination of a well-known ex-yakuza crime lord. The King of Killers is able to quickly bypass the criminal's defense systems, incapacitating the boss's bodyguards and isolating his prey. In a desperate bid for money, the criminal boss pledges to quadruple whatever the King of Killers is being paid to kill him, then warns the vigilante that he will be avenged by a vast revenge fund. The King of Killers ignores his pleadings and silently murders the crime boss.
Jet Li plays Fu, the film's central character, a superb melee fighter who is also a naive and inexperienced hitman in training who finally becomes the new King.
Officer Chan Kwan is played by Simon Yam, a talented and dedicated detective who is also the violent vigilante King of Killers.
Ngok Lo, played by Eric Tsang, is a self-described "rat bastard" who pays his rent by any means necessary and is a notorious liar and cheater.
Gigi Leung plays Kiki, Ngok Lo's daughter, a smart and beautiful lawyer who is fed up with her father's misdeeds.
Sato Keiji plays Eiji Tsukamoto, a vicious yakuza member on the hunt for his grandfather's assassin.
Tsukamoto's lead bodyguard and a skilled, if not cheap, fighter is played by Paul Rapovski.
Martin is played by Ip Kwong Kim, a revenge fund lawyer who isn't above lying to make a profit.
Tsukamoto's bodyguard, Hideri Meiken, plays Sasaki, a Japanese karate practitioner.
