InternationalThe review
Fritz Lang's first sound film is one of the most influential thrillers ever made — a landmark of German Expressionism that critics consistently rank among the greatest films of all time. Its premise has a grim symmetry: a city's police force and its criminal underworld launch parallel manhunts for the same child murderer, and Lang crosscuts between their near-identical, smoke-filled strategy sessions to make plain how much the law and the mob resemble each other. The craft is staggering — expressionist shadow and composition, a camera that prowls through Berlin's seediest corners, and, most pioneering, a sound design built around a single whistled tune, letting audio carry meaning decades before that became routine. Peter Lorre's performance, a study in pathetic menace, is treated by most critics as one of the great turns in cinema, and the film's famous climactic confrontation gives him a speech that still provokes argument.
If the film has weaknesses, they are largely products of its era. Some contemporary reviewers found it overlong, with repetitions and slow stretches, and even admirers concede that the climactic kangaroo-court scene is a static, talk-heavy set piece that asks a great deal of a modern audience. Early-sound technology constrains the performances — much of Lorre's work is physical and near-silent until the end — and the film's psychoanalytic framing of the killer's compulsions reads as dated, even though Lang pointedly refuses to explain or excuse him. What one viewer calls restraint another calls staginess.
The film's true subject is a society under stress: a public panicked enough to trade due process for vigilante certainty, institutions that mirror one another across the law's dividing line, and the unbearable question of whether a man who cannot control his compulsions can be judged — or should be. Critics have never agreed on what the trial scene argues, some reading it as a cold brief for the death penalty and others as an anguished plea for the killer's humanity; that split says as much about the viewer as about the film. Contemporary moralists objected to the subject matter itself, while today's near-unanimous verdict is that Lang turned taboo material into a technically astonishing, morally serious masterwork. The murders themselves are never shown, which is both the film's restraint and part of its dread.
Who it's for
Students of film history and German Expressionism; fans of film noir and the psychological thriller (this is effectively the genre's founding document); viewers who want procedural structure with real moral weight; admirers of Peter Lorre; anyone curious how early sound film reinvented itself overnight. Its social commentary — on vigilantism, institutional panic, and mob psychology — keeps it relevant to contemporary viewers well beyond the cinephile niche.
Who it's not for
Viewers for whom the subject of crimes against children is unwatchable regardless of how tastefully it's handled; anyone needing fast pacing, action set pieces, or modern production values; audiences who bounce off black-and-white, subtitled 1930s films; and anyone seeking a clear-cut hero to root for — *M* deliberately leaves you standing with no one at all. — implied child murder (offscreen) · disturbing subject matter · menacing pursuit of a child · violence (mostly offscreen) · mob justice/vigilantism · heavy, bleak themes
Birds of a feather...
- Film12 Angry Men (1957)
Shares with M a relentless interrogation of justice as a human institution: both turn procedural deliberation into suspense, force viewers to sit with moral ambiguity rather than resolution, and show how group logic and prejudice can steamroll individual rights. The claustrophobic, dialogue-driven approach is the tonal cousin of M's procedural unease.
85% - FilmThe White Ribbon (2009)
Both are German films examining how a community's panic and moral fear can incubate authoritarian solutions; both share a stark black-and-white visual style, deep moral ambiguity, and a refusal to offer clear answers.
85% - FilmThe Third Man (1949)
Lang's expressionist portrait of a city gripped by moral hysteria shares The Third Man's obsession with institutional corruption and the blurring of justice and vengeance. Both films use skewed angles, shadowy compositions, and an ambiguous central figure to force viewers into complicity with the mob's logic, refusing easy verdicts.
85% - FilmSe7en (1995)
Both are procedural chases after a serial killer that become inquiries into a society's own rotten logic; the line between law and crime blurs, and neither offers a cathartic verdict.
85% - FilmThe French Connection (1971)
A landmark parallel to French Connection's moral equivalence: both show police and criminals mirroring each other's methods in a corrupt, fearful city. M's procedural slog, ambiguous ending, and refusal to offer a moral foothold align closely with the source's tone and themes.
85% - FilmTwo Prosecutors (2025)
Both are portraits of justice systems that destroy individuals through ordinary bureaucratic process rather than overt villainy. This film's patient, administrative dread and refusal of catharsis mirror M's indictment of a society where procedure itself becomes indistinguishable from oppression, and both leave the viewer without a clear moral foothold.
84% - FilmSunrise: A Song of Two Humans (1927)
Shares Sunrise's German Expressionist lineage: both use shadow, skewed angles, and visual atmosphere to externalize moral conflict. While Sunrise charts a path from guilt toward redemption, M refuses resolution, but both films are invested in the psychology of transgression and the mechanisms of judgment. A viewer drawn to Sunrise's visual poetry and dark undercurrents will find a kindred work in M's chiaroscuro of conscience.
80% - FilmZodiac (2007)
A city-wide manhunt for a serial killer that becomes a study in institutional panic and the blurring of justice and vengeance; like Zodiac, it is procedural, atmospheric, and refuses clear moral answers.
80% - FilmVertigo (1958)
For viewers drawn to M's atmosphere-over-action approach, this is a natural fit: both are formalist studies of obsession and compulsion, using recurring motifs, music, and subjective visual style to pull the audience into an unstable psyche. Neither offers easy psychological or moral answers.
70% - FilmNightcrawler (2014)
A society's panicked response to a murderer exposes the machinery of justice and mob logic. Both films are morally ambiguous, refuse easy answers, and use atmospheric craft to explore systemic rot.
70% - FilmDouble Indemnity (1944)
Both share the fatalistic grammar of noir: a morally compromised protagonist, an oppressive atmosphere, and a procedural unraveling that feels inevitable. The insurance-investigation logic parallels M's bureaucratic apparatus, and both films use sound and shadow to externalize guilt and complicity rather than explain them away.
68% - FilmMemento (2000)
A morally ambiguous world where justice and vengeance blur, and the audience is denied a comfortable vantage point. Both films explore a disturbed psyche from within, using atmosphere and ambiguity to provoke unease.
