The Camera Is an Accomplice: A Century of the Serial-Killer Film

The serial-killer film has never really been about killers. From its very first frame, it has been about watching — about what it means that we, sitting safely in the dark, want to look at this at all. That is the secret history this course traces: ten films across seventy-six years that keep asking the same uncomfortable question in new formal languages, each one inventing a technique for making the audience feel the weight of its own gaze. The line runs from a balloon caught in telephone wires in Weimar Berlin to a fluorescent-lit hardware basement in California, and at every station, the real invention is not a new kind of monster. It is a new way of implicating you.

M (1931)
dir. Fritz Lang · Peter Lorre, Ellen Widmann, Inge Landgut

Everything starts here, and it starts with an act of restraint. Lang, working in the first years of sound, films his killer's crimes by not filming them: a child's ball rolls out of the grass and stops; a balloon snags in the telephone wires; a mother calls a name up an empty stairwell. The film hands you the edges of an event and trusts you to assemble the center, which means that from minute one, you are not a spectator but a collaborator. Watch also what Lang does with the new technology of sound — a whistled tune becomes a character's signature, identification carried by the ear rather than the eye, something silent cinema literally could not do. Shot by Fritz Arno Wagner, who had photographed the deep shadows of the great German silents, M takes the distorted, night-world style of the 1920s and cools it into something closer to reportage: the city itself, cross-cut between police and underworld both hunting the same man, becomes the film's true protagonist. Every film in this course is, one way or another, an argument with M.

Psycho (1960)
dir. Alfred Hitchcock · Anthony Perkins, Janet Leigh, Vera Miles

Thirty years later, Hitchcock takes Lang's lesson — that the audience's imagination is the sharpest instrument in the toolbox — and welds it to the machinery of the American studio picture. He shot it fast and cheap with his television crew in stark black and white, at a moment when prestige Hollywood meant color and gloss, and that stripped-down look is itself a statement: this story lives in motels and back offices, not manors. The technique to watch is the point of view: Hitchcock keeps sliding you behind characters' eyes — through a windshield, through a peephole — so that you are always looking with someone before you have decided whether you should. And in one bathroom, he demonstrates what editing alone can do: dozens of camera setups in under a minute, violence built entirely from fragments and cuts, the mind stitching together what the frame never quite shows — Lang's off-screen principle, accelerated into a storm of splinters. It also inherits M's most radical move: extending psychological interiority, even a kind of terrible sympathy, to the figure the genre had always kept at arm's length.

M (1931)
dir. Fritz Lang · Peter Lorre, Ellen Widmann, Inge Landgut

The same year, in London, Michael Powell made Psycho's dark twin — and it ended his British career. Where Hitchcock implicates the audience by stealth, Powell does it by declaration: his killer is a filmmaker, his weapon is mounted on his camera, and a small mirror bolted beside the lens forces his victims to watch their own fear as it is recorded. Filming and killing become the same gesture, which makes every member of the audience — anyone who has paid to watch fear on a screen — part of the mechanism. Note the color: Otto Heller shoots the film in hues that are lush and lovely in ways that feel wrong for the material, a deliberate refusal of both Gothic shadow and the gritty realism then sweeping British cinema. Powell tells you who the killer is almost immediately, trading mystery for complicity — a structural gamble inherited from M — and audiences of 1960 could not forgive him for it. Nearly every film after this point in the course is descended from his mirror.

M (1931)
dir. Fritz Lang · Peter Lorre, Ellen Widmann, Inge Landgut

Made in Chicago for almost nothing, far from Hollywood and far from the masked-killer thrillers then filling drive-ins, Henry strips the genre down to the studs. No suspense music, no mystery, no explanation: just flat light, real locations, and a man who is terrifyingly ordinary. Its great formal invention is a series of static shots — victims held in the frame like evidence photographs, unmoving — while the soundtrack carries the audio of violence from another moment in time. Picture and sound are pulled apart, and the horror happens in the gap between them, in your head; it is Lang's off-screen murder rebuilt as an act of deliberate cruelty toward the viewer's imagination. And in its most notorious passage, a camcorder enters the story, so that watching the film means watching a recording the killers made to watch themselves — Powell's camera-as-weapon, updated for the home-video age and pointed straight back at the couch.

M (1931)
dir. Fritz Lang · Peter Lorre, Ellen Widmann, Inge Landgut

The same year, at the opposite end of the industrial spectrum, Michael Mann built the serial-killer film's glossy modern engine. With cinematographer Dante Spinotti he composes in cold blues, teals, and clinical whites — wide, symmetrical, architectural frames borrowed from advertising and design culture — and sets the whole thing pulsing to synthesizers. The invention that mattered most: the profiler, an investigator whose method is empathy, who studies a murdered family's home movies in a dark room and tries to stand inside the killer's way of seeing. The hunt is no longer a chase through streets, as in M; it is a contest of gazes, and the danger is that looking through a killer's eyes might be a door that doesn't close behind you. Every consulting-a-brilliant-caged-killer scene in the decades since — including the famous ones five years later — was drafted here first.

M (1931)
dir. Fritz Lang · Peter Lorre, Ellen Widmann, Inge Landgut

Demme takes Mann's blueprint and rewires it around a single, radical camera decision. Cinematographer Tak Fujimoto films conversations almost straight down the lens: when men address Clarice Starling — appraising her, condescending to her, sizing her up — they look nearly at you, and for the length of the shot you stand exactly where she stands. The genre's oldest subject, the predatory gaze, is no longer depicted; it is administered, shot by shot, to the viewer. This is Powell's mirror achieved without a mirror, and M's audience-collaboration made physical. The film also marks the moment the serial-killer picture became prestige cinema — serious craft, serious acting, mainstream awards — which set the commercial stage for everything in the 1990s that followed.

M (1931)
dir. Fritz Lang · Peter Lorre, Ellen Widmann, Inge Landgut

Then three Belgian film students blew the whole edifice up. Shot in handheld black and white in the grammar of documentary — boom mics dipping into frame, crew members answering when the killer chats to them, reframing on the fly like news footage — the film follows a charming murderer being profiled by a camera crew that never intervenes. It is a fake documentary that turns the documentary's promise of truth into a trap: the "neutral" camera is revealed, scene by scene, as a participant, and your own continued attention (and, horribly, your laughter — the film is a pitch-black comedy) is part of the crime. It is Henry's camcorder sequence expanded to feature length, Powell's thesis restated as deadpan Belgian absurdism, and the most explicit statement of this course's argument: to record is to take part.

Se7en (1995)
dir. David Fincher · Morgan Freeman, Brad Pitt, Gwyneth Paltrow

Fincher's breakthrough returns the genre to the studio system and gives it its definitive modern look. Darius Khondji lights an unnamed, perpetually rain-soaked city almost entirely from sources you can see in the frame — a bare bulb, a flashlight beam — letting everything else fall into engulfing darkness; that visual language colonized crime cinema for a decade. The structural invention is the killer as author: each crime scene arrives captioned with a word, arranged like a text, so that the detectives — and you — must read rather than chase. An aging detective does his hunting in a library at night, filling index cards, and the film dares to make research its central action. It is the thinking-game of M's underworld manhunt, restaged as gothic scholarship, and its refusal of easy comfort reintroduced genuine moral seriousness to the multiplex thriller.

M (1931)
dir. Fritz Lang · Peter Lorre, Ellen Widmann, Inge Landgut

From the new wave of South Korean cinema — newly free of censorship, protected by screen quotas, suddenly world-class — comes the film that turns the procedural inside out. Bong and cinematographer Kim Hyung-goo shoot in wide frames where the landscape carries as much weight as the people: a crime scene in an irrigation ditch is approached with a slow lateral drift, the rice paddies given equal billing with the investigators. The subject is not the killer but the investigation itself as a broken instrument — a 1980s provincial police force whose methods (including coerced confessions) cannot produce reliable truth, in a country whose authoritarian machinery is visible at the edges of every scene. Where Se7en's detectives read a legible text, Bong's detectives stare at a world that refuses to become one. The film moves between farce and dread within single shots, a tonal range no earlier film in this course attempts, and it made the serial-killer film a vessel for national history.

Zodiac (2007)
dir. David Fincher · Jake Gyllenhaal, Mark Ruffalo, Anthony Edwards

Fincher returns, twelve years after Se7en, having absorbed the very lesson Memories of Murder taught: the deepest horror is not the crime but the not-knowing. Shot by Harris Savides in available light, faces half-swallowed by shadow in newsrooms and police bullpens, Zodiac is a procedural about procedure — decades of letters, files, handwriting samples, and jurisdictional dead ends, rendered with fanatical period accuracy in the visual manner of the great paranoid American films of the 1970s. Its subject is obsession as a form of attention that produces knowledge without producing meaning: the film's most electric scene is simply a man standing in a hardware-store basement, certain, and unable to do anything with his certainty. Where M opened this course with a whole city mobilized into action, Zodiac closes it with individuals who can see everything and act on nothing — the genre's founding engine, run in reverse.


Watch these ten in order and you watch the genre argue with itself for three-quarters of a century. Lang establishes the two poles in a single film — the unseen crime that makes your imagination the crime scene, and the manhunt that makes society itself the protagonist — and everything after chooses a lane. One line runs through Psycho, Peeping Tom, Henry, and Man Bites Dog, each pushing harder on the guilty intimacy between camera and viewer until the camera literally joins the crew. The other runs through Manhunter, The Silence of the Lambs, Se7en, Memories of Murder, and Zodiac, following the investigators, and it bends steadily from confidence toward doubt — from profilers who can enter a killer's mind to detectives left holding files no one can close. The techniques these films invented — the off-screen crime, the fragmented cut, the killer's-eye lens, the evidence-photo tableau, the practical-light darkness, the landscape-swallowed corpse — long ago escaped the genre and became part of how movies think. But the founding question has never been answered, only rephrased: it was there in 1931, in an empty stairwell, when Lang first made the audience do the killing's imagining. It has been our balloon in the wires ever since.
