M and the Sound of a City in Pursuit
Lang's early sound manhunt is explained for revival audiences, from Dusseldorf panic to the trial scene, plus notes on sound, crowd psychology and care.

You will learn how M ties early sound craft to panic on the streets of Berlin and to a long trial scene that stays careful rather than lurid. M is a 1931 German mystery thriller directed by Fritz Lang, written by Lang and Thea von Harbou, and it follows both the police and the criminal syndicates as they hunt a child murderer played by Peter Lorre.
Why M still holds in a small hall
M runs 111 minutes, in German, and it was released on 11 May 1931. It was produced by Seymour Nebenzal for Nero-Film A.G., distributed by Vereinigte Star-Film GmbH, photographed by Fritz Arno Wagner and edited by Paul Falkenberg. The leads are Peter Lorre as Hans Beckert, Otto Wernicke as Inspector Karl Lohmann and Gustaf Grundgens as Der Schranker. For you as a programmer, the useful fact is restraint. Lang shows no act of violence or death of a child on screen. He later said that by only suggesting violence he forced each member of the audience to create the details according to their personal imagination. That choice keeps the film playable for a mixed audience, and it lets you introduce the story as procedure and pressure, not as shock.
What do you hear before you see
M was Lang's first sound film and he treated sound as structure. You hear off-camera sounds, sounds that motivate action, and stretches of silence set before sudden noise. Because sound could carry story information, Lang could use fewer cuts. The film also uses long tracking shots, which you can point out before the lights go down so that viewers watch movement through streets, stairwells and offices. For practical planning, finding a print or DCP and running a small screening starts with the same question you ask here: which sound cues will your room reproduce clearly and which will get lost if the level is low.
A city under pressure
The opening stays in Berlin. Children play an elimination game with a chant about a child killer. Frau Beckmann waits for her daughter Elsie. A wanted poster warns of a killer who preys on children while parents wait outside a school. Elsie leaves school bouncing a ball. Beckert approaches her while whistling "In the Hall of the Mountain King" by Edvard Grieg, offers a balloon bought from a blind street vendor, and walks with her. Then her place at the table stays empty, her ball rolls through the grass, and her balloon catches on telephone lines before blowing away. When Beckert sends an anonymous letter to newspapers claiming the murders and promising more, the police turn to fingerprinting and handwriting analysis. Under government pressure they work around the clock, and Lohmann orders checks of recently released psychiatric patients with a history of violence against children.
How does the hunt mark its man
Police raids in seedier districts disrupt organized crime, so Der Schranker calls the bosses of the Ringvereine to a conference and the underworld starts its own manhunt with beggars assigned to watch children. The police search Beckert's rented room, find evidence linking him to the letter and to a past crime scene, and wait to arrest him. On the street, Beckert follows a girl seen in a shop window reflection, then stops when her mother appears. He befriends another girl, but the blind vendor knows the whistle and warns a friend. The friend tracks Beckert to a shop, then chalks "M for Morder" on his palm, pretends to trip, and bumps Beckert to mark the back of his overcoat. You can read the full plot and cast list to track each step without losing the thread during discussion. The girl sees the chalk and offers to clean it, but Beckert understands he is watched and runs without her.
The office building trap
Beckert hides in a large office building just before workers leave for the evening. The beggars alert Der Schranker, who arrives with other criminals, questions watchmen, and searches the building to the attic where Beckert is caught. One watchman trips a silent alarm, the criminals escape with their prisoner just before police arrive, and Franz, one of the criminals, is left behind. Lohmann falsely tells Franz that a watchman was killed, which leads Franz to admit that finding Beckert was the only motive and to reveal the plan. The episode matters because Lang roots it in documented Berlin life. His depiction of the underworld drew on the real Ringvereine, formally wrestling associations that projected a respectable image while operating as organized crime with a board structure and support for families of imprisoned members. The office break-in drew on the 1929 break-in at the Disconto Bank in Berlin by the Sass brothers' gang, though that real case aimed at larceny.
Who gets to judge in the distillery
The criminals take Beckert to an abandoned distillery for a kangaroo court before a large silent crowd. He is given a defender who argues but wins no sympathy. Beckert says he cannot control his urges while the others break the law by choice, and he asks by what right they judge him. He describes fire, voices and torment, and he pleads to be handed to the police. His defender notes that Der Schranker, who presides, is wanted on three counts of manslaughter, and argues it is unjust to execute an insane man. Police enter just as the crowd moves to kill Beckert, and they arrest both Beckert and the criminals. A panel of judges then prepares a verdict while the mothers of three victims weep. Frau Beckmann says no sentence will bring the dead children back, that one has to keep a closer watch over the children, and the screen fades as she adds, "All of you."
Which version should you request
Versions differ, so check listings line by line. M premiered at the Ufa-Palast am Zoo in Berlin in a 117-minute version. The original negative is preserved at the Federal Film Archive in a 96-minute version, a 98-minute edited version appeared in 1960, and a restoration in 2000 by the Netherlands Film Museum with the Federal Film Archive, the Cinemateque Suisse, Kirsch Media and ZDF and ARTE led to a 109-minute version issued by Janus Films as part of its Criterion Collection. A complete print of the English version and selected scenes from the French version were included in the 2010 Criterion Collection release. The film reached the United States in April 1933 through Foremco Pictures, played two weeks in German with English subtitles, then was replaced by an English-language version dubbed under Eric Hakim with Lorre among the few returning voices. Like many 1930 to 1931 talkies, it had been partly reshot for foreign markets, with an English version released in 1932 built from an edited script and a French version in which Lorre's speaking parts were dubbed. A 2013 DCP from Kino Lorber played in North America in 1.19 to 1 at 111 minutes after restoration by TLEFilms Film Restoration and Preservation Services in Berlin with Archives francaises du film CNC in Paris and PostFactory GmbH in Berlin. Early response noted length, with a Variety review saying that cutting could be done without harm, while Graham Greene likened the film to looking through a microscope at a tangled mind. Roger Ebert added the film to a Great Movies list in 1997 and stressed Lang's limited use of dialogue at a time when many sound films talked without pause.
