Vengeance (Chinese: 復仇) is a 2009 neo-noir crime film directed by Johnnie To from a screenplay written by Wai Ka-Fai. A co-production between Hong Kong and France, Vengeance features an international ensemble cast that includes Johnny Hallyday, Sylvie Testud, Simon Yam, Anthony Wong, Lam Suet, Lam Ka-Tung, Maggie Siu, and Cheung Siu-Fai. The film was co-produced by ARP Sélection in France, along with Hong Kong production companies Media Asia Films, and Milkyway Image.
Vengeance tells the story of François Costello, a French assassin-turned-chef whose daughter, son-in-law and grandchildren are murdered by a gang of Triads. Costello heads to Hong Kong to embark on a violent quest for revenge, enlisting the aid of three hitmen. The film features To's trademark use of stylized violence, along with elements of both film noir, and heroic bloodshed, a sub-genre of Hong Kong action cinema.
The idea of Johnnie To directing an English-language film originated with the ARP co-founders and French producers Michèle and Laurent Pétin, who had Alain Delon in mind for the lead role. In 2006, after the Pétins approached him with their idea, To met with Delon, who was not interested in making the film. The Pétins later recommended Johnny Hallyday, and Hallyday was cast in the lead role after meeting with the director in early 2008. Principal photography for Vengeance began in November 2008, and concluded in February 2009; filming took place in Hong Kong and Macau, with a crew mainly based in Hong Kong. Vengeance competed for the prestigious Palme D'Or award at the 62nd Cannes Film Festival, and was released theatrically in France on 20 May 2009, following its positive critical reaction at Cannes. The film was released theatrically in Hong Kong on 20 August 2009, and premiered in North America at the 2009 Toronto International Film Festival.
