Then came 2003’s Infernal Affairs III . Critics called it convoluted. Fans called it confusing. Martin Scorsese, who would remake the first film as The Departed , reportedly found the third installment difficult to follow.
This timeline takes place months before the events of the first film. It explores the hidden relationship between the tragic undercover cop Chan Wing-yan (Tony Leung Chiu-wai) and a mysterious mainland Chinese security official named Shen澄 (Chen Daoming). It also delves into Chan’s therapy sessions with Dr. Lee Sum-yee (Kelly Chen), offering a rare glimpse of warmth and hope in Chan's otherwise grueling double life.
Infernal Affairs III did not seek to replicate the sleek, crowd-pleasing pacing of the first film, nor the sweeping historical epic feel of the second.

The film cuts between these two eras without warning, without title cards, without mercy. A scene of Ming eating lunch cuts to a scene of Chan bleeding. A conversation with Dr. Lee dissolves into a conversation with Hon Sam. The audience is disoriented. That is the point. We are trapped inside Inspector Ming’s deteriorating mind. Martin Scorsese, who would remake the first film

Released in 2003, just one year after the original groundbreaking hit, (无间道III: 终极无间) serves as the ambitious concluding chapter to one of the most celebrated trilogies in Hong Kong cinema.
