A reading · through the lens of theory

Begin with the small mirror. Powell bolts it to the side of Mark Lewis's camera so that the woman he is killing sees, in her final seconds, her own face stretched with terror. He is filming her fear; the mirror forces her to watch herself supply it. Hold that object in your mind — a lens and a mirror mounted together, recording and reflecting in the same instant — because the whole film is folded inside it.

Mark works at a film studio by day and photographs women at night, and in his attic he is shooting a documentary about fear, with a blade hidden in his tripod leg. We learn this almost at once. That early disclosure is the first thing to understand about how the film operates on you, and Deleuze gives it a name. He calls the cinema of the knowing audience the relation-image, or mental-image: meaning that nobody on screen possesses, assembled instead by a viewer holding the missing relation. Here that relation is a murder weapon. Helen, the warm girl downstairs, sees a shy man with a camera; we see the spike. The dread in Powell isn't mystery, it's the distance between what she reads in Mark and what we already know. He inherited this exactly — from Lang's M, where we know the killer before the city does and are made to identify rather than simply judge, and from Hitchcock's Rear Window, which built an entire film out of one man's sightlines and quietly enlisted us as his fellow watchers. Powell takes the inheritance and sharpens the apparatus into a knife.

Then there is the other looking, the one stacked inside itself. Watch the scenes where Mark reviews his kills on the little screen in his flat. The editing, by Noreen Ackland, holds on his face at least as long as on the footage. So the camera is perceiving a man who is perceiving his own camera's record of a woman perceiving her own death in a mirror. Deleuze's term for an image that shows us perception perceiving itself, that lets us feel the camera's own presence as a seeing thing, is the dicisign. Most films hide the act of looking inside the story; Peeping Tom makes the act of looking the story, and Powell didn't borrow that reflexivity from genre at all. He took it from Vertov's Man with a Movie Camera, where the operator's body and the cutting bench appear inside the film as its true subject. What Vertov made joyous, Powell makes lethal. The apparatus that films life becomes the apparatus that ends it, and the camera-with-mirror is the precise hinge.

Why does Mark do it? The script by Leo Marks supplies a cause, and here a different Deleuzian region opens, the impulse-image — his cinema of naturalism, where a person is driven downhill by an appetite older than any social reason. Mark's father, a scientist, conditioned him with fear experiments and filmed the boy's terror; Powell casts himself as that father in the home-movie inserts, which implicates the director in the very crime of looking. Mark's murders are symptoms in Deleuze's strict sense, acts that discharge a buried drive rather than answer a situation. The camera is his fetish, the part-object charged with all the compulsion, so saturated that he cannot photograph without wounding. Heller's cinematography matters precisely here: the boarding house is airy, the Eastmancolor warm and domestic, and that misleading normality is what Deleuze would call the derived milieu hiding an originary world, a savage substrate of pure drive beneath the ordinary surface. And the whole thing runs on a line of slope, an irreversible descent. The only place it can end is Mark turning the spike on himself while his cameras record it — director and subject of one last film, watched by Helen and, through her, by us. The circuit closes with a literalism that is philosophical rather than melodramatic.

That ending is why the film mattered and why it cost Powell his career. British critics didn't recoil because it was gory; it isn't, especially. They recoiled because it refused them the exit. Psycho arrived weeks later and faced the identical problem — how to seat the audience in the killer's chair — and solved it through fast cutting that shatters the moment of the shower into fragments you can't quite hold. Powell did the opposite. He used long takes and real-time duration to keep you inside Mark's looking with no edit to release you. Two films, one problem, opposite craft. Out of that decision the slasher's killer-POV descends, and so does every later film nervous about its own appetite for watching.

So go back to the mirror. Powell's real invention was to stop treating the camera as neutral furniture and make it a body, a desire, a weapon, and then to hand it, lens and mirror together, back to you. The film asks a question it will not close: when you watch, what exactly are you doing? Next time, notice how often you are looking at someone looking, and how comfortable that usually is.
