Fritz Lang’s M is a horror film that earns its dread the old-fashioned way: by showing a killer on the loose, not hiding behind gore. Peter Lorre plays Hans Beckert, a child-murderer whose crimes terrify Berlin so badly that cops and criminals alike join the hunt. The result is a thriller that still holds up as one of the greatest films ever made.

The Killer’s Whistle
Beckert is a monster, but Lorre makes him human enough to be feared rather than simply reviled. He whistles “In the Hall of the Mountain King” while luring children, and that tune becomes the film’s leitmotif — a signal that danger is near. His letter to the papers, taking responsibility for the murders and promising more, is a chilling touch. The film never shows the killings directly, which makes them feel more terrible.
Cops and Criminals Together
The hunt splits between two camps. Inspector Karl Lohmann leads the police, digging into fingerprints and handwriting samples from Beckert’s letter. The criminal underworld, led by Der Schränker (“The Safecracker”), organizes its own search, assigning beggars to watch children. That pairing is Lang’s boldest move — cops and crooks working side by side against a common enemy. It gives the chase a tension that few thrillers have matched since.
Berlin Under Siege
Lang builds the fear through simple, effective means:
- Wanted posters warn of the killer
- Parents wait anxiously outside schools
- Children play a grim elimination game in courtyards
- A balloon drifts free after Elsie’s disappearance
Every scene adds to the sense that something terrible is happening, and everyone knows it.
Lorre’s Breakthrough
M was Lorre’s first major starring role, and it launched him into a long career as a villain. He followed it with films like Mad Love and Crime and Punishment, where he was often cast as the bad guy. Before M, Lorre was mostly a comic actor. The film changed that, and it gave him a type that would follow him for years.
A Masterpiece
Lang’s direction is assured throughout. The film uses long tracking shots and a musical motif that became standard in thrillers to come. Lang himself regarded M as his greatest work, and it stands as proof. The hunt builds to a climax that delivers real suspense, not cheap shocks.
There is no wasted scene in M. Every frame serves the terror, the chase, the dread. It is a perfect example of a film knowing exactly what it wants to be and delivering it without compromise.
M earns its reputation. It is a masterpiece of the thriller genre, a film that understands fear better than almost any other in cinema.
