The first film, released in 2002, was a critical and commercial success, praised for its unique take on the undercover cop genre. The sequel, Infernal Affairs II, continued the story, delving deeper into the complexities of the characters and their situations.

Lead signatory: Inspector Lau Kin-Ming (Deceased). The file was a ghost. Everyone knew the official story: Lau Kin-Ming, a decorated hero, died a martyr in a shootout ten years ago. Ming also knew the other story—the one whispered in locked server rooms: that Lau had been a mole for the triads. And that the real hero, Chan Wing-Yan, had died forgotten, buried as a criminal. The label read: Closed – Operation Eden
If the first film was a duet between Andy Lau and Tony Leung, the third is a symphony. The addition of as the cold, calculating Inspector Yeung adds a chilling new dynamic. His performance is intentionally opaque, keeping the audience (and Lau) guessing about his true allegiance until the final act.
