Infernal Affairs -- Wú Jiàn Dào

Infernal Affairs (Chinese: 无间道, Pinyin: Wú Jiàn Dào) is a 2002 Hong Kong crime-thriller film directed by Andrew Lau and Alan Mak. It tells the story of a police officer who infiltrates the triads, and a police officer secretly working for the same gang. The Chinese title means "the non-stop way", a reference to Avici, the lowest level of hell in Buddhism. The English title is a word play combining the law enforcement term "internal affairs" with the adjective infernal. Due to its commercial and critical success, Infernal Affairs was followed by a prequel, Infernal Affairs II, and a sequel, Infernal Affairs III, both released in 2003.

Pre-release publicity for Infernal Affairs focused on its star-studded cast (Andy Lau, Tony Leung, Anthony Wong, Eric Tsang, Kelly Chen and Sammi Cheng), but it later received critical acclaim for its original plot and its concise and swift storytelling style. The film did exceptionally well in Hong Kong, where it was considered "a box office miracle" and heralded as a revival of Hong Kong cinema which at the time was considered to be direly lacking in creativity.

Miramax Films acquired the United States distribution rights of this film and gave it a limited U.S. theatrical release in 2004.

Infernal Affairs performed well at the 2002 Hong Kong Film Awards, beating Zhang Yimou's Hero for the Best Film award. It was ranked No. 30 in Empire magazine's "The 100 Best Films Of World Cinema" in 2010.

In 2003, Plan B Entertainment acquired the rights for a Hollywood remake, titled The Departed, which was directed by Martin Scorsese, and starred Leonardo DiCaprio, Matt Damon, Jack Nicholson, and Mark Wahlberg, set in Boston, Massachusetts, roughly based on the life of famed Boston mobster James "Whitey" Bulger. The Departed was released on 6 October 2006 and went to critical acclaim and won the Academy Award for Best Picture.
