Trivia

Jump to: Spoilers (2)
When Yan and SP Wong are waiting at the elevator, the digital floor counter skips the 4th floor. In China and Hong Kong, the number 4 is considered bad luck because it sounds similar to the word 'death'.
When referencing this film as the inspiration for the Best Picture-winning The Departed (2006), the announcer at the 79th Academy Awards mistakenly identified the Hong Kong production as Japanese.
The psychiatrist's name, "Lee Sum Yee", is a homophone (in Cantonese) for "your psychiatrist".
Martin Scorsese, director of The Departed (2006), claims he was unaware that his film was a remake of this one during filming.
The English title is a play on words mixing Ming's job in the IA, the infernal nature of both characters' double lives, and finally Dante's Inferno, relating to the original Cantonese title.
Tony Chiu-Wai Leung and Anthony Chau-Sang Wong were both in Hard Boiled (1992), where Leung also played an undercover cop. In both films, he receives a gift from a superior officer, (a cigarette lighter in that film and a watch in this one).
