Infernal Affairs (film series)
crime thriller film series
Infernal Affairs is a series of three crime drama films directed by Andrew Lau and Alan Mak, starring Andy Lau and Tony Leung. 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".
The Criterion Collection released the trilogy as a box set on November 15, 2022.

Infernal Affairs (2002)
Infernal Affairs focuses on a police officer named Chan Wing-yan (Tony Leung), who goes undercover into a triad, and a triad member Lau Kin-ming (Andy Lau), who infiltrates the Hong Kong Police Force. Each mole has been planted by the rival organisation to gain an advantage in intelligence over the other side. The more the moles become involved in their undercover lives, the more issues they have to cope with.
The prologue opens with the introduction of triad boss Hon Sam (Eric Tsang) ("Brother Sam"), who sends a number of young gangsters to the police academy as moles, among them a young Lau. Concurrently, a young Chan joins the police force but is seemingly expelled from the academy even though he manages to impress Superintendent Wong Chi-shing (Anthony Wong).

Why this record matters
“Infernal Affairs (film series)” is worth following because a concise public description often conceals a longer documentary argument. Here, Infernal, Affairs and film provides the most credible route into that argument.
Object files, edition statements, performance records and contemporary criticism preserve different stages of the work’s history. The source revision retrieved here is dated Mar 26, 2026. The linked authority identifier is Q6029465. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2022 and 2002.
Later fame can flatten the distinction between original context, subsequent adaptation and institutional collecting history. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
