The 39 Steps · essays & theory

A reading · through the lens of theory

The landlady opens her mouth to scream, and what comes out is a train whistle. The body on the floor of Hannay's flat, the discovery, the horror — all of it is yanked, in one frame, three hundred miles north onto the Flying Scotsman. You barely register the trick before the film has put it to work, and the work is simple: keep you running.

That cut is the whole picture in miniature, and it's worth slowing down on the one thing Hitchcock refuses to slow down on. Deleuze split cinema into two regimes. In the movement-image, someone perceives a situation and acts to change it; perception spills into action, and the edit serves that chain. In the time-image — the postwar cinema of Antonioni, Resnais — the link snaps, and the character can only look and endure, with no act equal to what they see. The 39 Steps sits at the very peak of the first regime. Nothing here is endured. Everything is converted into motion, even a scream.

Give the chase its Deleuzian name and it sharpens. A global situation — a spy ring lifting state secrets out of Britain — bears down, and it will take one decisive act to discharge it: a man in a music hall shouting a question Mr. Memory cannot stop himself from answering. That is the large form of the action-image, situation pressing until an act transforms it. The thing pressing is everywhere and nowhere, an encompasser you feel without seeing: the "organisation," the missing finger across the room, the policeman at the door. And the stolen specifications themselves? Their content is nothing — a melody, a set of plans, it scarcely matters. Hitchcock's MacGuffin is a pure pretext, an empty term whose only job is to set bodies in motion.

Notice the figure Hannay's flight actually draws. A London flat, a sleeper car, the Forth Bridge, open moor, a crofter's lamplit cottage, Professor Jordan's drawing room, a political stage, a country inn. These spaces share nothing but the man crossing them. Deleuze calls that stitched zigzag the vector, the "line of the universe" — a trajectory that links milieus with no common world. The film breathes along it, swelling out to the vast Highland emptiness and then drawing tight again to the thread of the pursuit, a rhythm Deleuze names respiration-space: the big skeleton of the country, the taut line of the hunt.

Then the turn that makes this more than a brilliant adventure. Deleuze gives Hitchcock a singular seat in the history of the movement-image: he is the one who completes it by folding in the relation-image, the mental-image. The shot stops being only what a character sees and does; it becomes a net of relations held by us. We know Hannay is innocent. We know the genial host is the spy. Suspense is precisely that gap between what the audience knows and what the man on screen doesn't — knowledge made dramatic, the spectator installed as a knowing third party. After Hitchcock, an image can think a relation, not just report an action.

Watch how he builds those relations out of plain objects. Professor Jordan is urbane, respectable, fatally calm — and missing the top of one finger. That finger is a demark: an anomaly that breaks the customary chain and forces you to read the man against his manners. Against it runs the mark, the object that means by habit — when you see X, expect Y. Mr. Memory's compulsion to answer any question is a mark; the tune lodged maddeningly in Hannay's head is a mark that turns out to carry the entire secret. And the handcuffs that chain Hannay to Pamela at the inn are a symbol — Deleuze's own example from this film — an object that condenses the picture's organizing relation. A bond imposed (captor and captive) slowly becomes a bond chosen (the couple). The cuff does the romance's argument for it.

Place the famous scream cut in its lineage and the debts come clear. The collision that flips horror into momentum — scream graphically and aurally rhymed with whistle, two shots striking a third meaning — is Soviet montage repurposed, Potemkin's method smuggled into a Gaumont-British thriller. The unseen controlling network descends from Lang's Mabuse; the wrongly accused innocent from Hitchcock's own Lodger; the plot-active sound bridge from his Blackmail. He gathered these and fused them into a single propulsive object, then seeded a century with it — every innocent-man-on-the-run picture, every romantic spy caper, runs on this engine.

What did it do to film as an art? It proved suspense is a structure of knowledge, not merely incident — that you frighten an audience most efficiently by telling them more than the hero knows, then making them wait. It showed the movement-image could carry wit, irony, a whole erotic comedy, and still move like a bullet. And by turning the screen into a field of relations the viewer must hold, it pointed cinema toward thinking — toward the mental-image Deleuze saw as Hitchcock's gift to the form.

Watch it again for one thing: the distance between what you know and what Hannay knows. The film lives in that gap. Hitchcock found out it was the most thrilling place in cinema to stand.
