Every child in one classroom gets out of bed at the same minute, opens the front door and runs into the dark. All of them except one. That is the premise of Weapons, and it is the best thing about the film: an image so simple and so wrong that it lodges in your head before the first chapter is over. Zach Cregger, who wrote and directed it, knows exactly how strong that hook is, and he spends a little over two hours turning it over like a stone to see what crawls out from underneath.

What crawls out is a good horror film, at times a very good one, and not the instant classic that part of its reception announced. Weapons is clever, well acted and often genuinely frightening. It is also a film whose structure is more exciting than its destination. Both things are true, and the second one does not cancel the first.

Weapons review: one classroom, one empty desk, one suspect

The setup is pure suburban nightmare. The pupils of a third-grade class vanish in the small hours of the same night, and the only one left behind is a quiet boy named Alex (Cary Christopher). Their teacher, Justine Gandy (Julia Garner), becomes the town’s first suspect almost by default: somebody has to be responsible, and she is the one adult every missing child had in common. Archer (Josh Brolin), a father whose son is among the missing, wants answers she does not have.

Cregger tells the story in chapters, each one following a different character through the same stretch of days: the teacher, the father, a police officer (Alden Ehrenreich), a young drifter on the town’s margins (Austin Abrams), the school principal (Benedict Wong) and, finally, Alex. Events overlap, a scene glimpsed from one angle returns from another, and the picture assembles itself piece by piece. The crisscrossing design recalls Paul Thomas Anderson‘s Magnolia more than any horror film, and it is the most original thing here after the premise itself.

The craft is confident. Larkin Seiple, the cinematographer of Everything Everywhere All at Once, shoots the neighbourhood’s lawns and porches at night as if they were already crime scenes, and the score, composed by Cregger with Ryan and Hays Holladay, knows when to stay out of the way. Cregger came to filmmaking from sketch comedy, as one of the founders of The Whitest Kids U’ Know, and it shows in his timing. He understands that a laugh and a scare are built the same way, with a setup, a pause and a payoff, and Weapons gets plenty of both, sometimes in the same shot.

The cast, and an Oscar-winning surprise

Julia Garner plays Justine as somebody who is difficult in exactly the ways that make her believable: defensive, a little reckless, not built to be the sympathetic heroine the plot seems to need. Brolin gives Archer the blunt, wounded fury of a man who has turned grief into an investigation, and Ehrenreich supplies much of the film’s comic relief as a cop who keeps making his own life worse.

The performance people remember, though, is Amy Madigan’s as Aunt Gladys. It won her the Academy Award for Best Supporting Actress, the film’s only Oscar nomination, after she had also taken the Actor Award. Saying more about Gladys would spoil one of the film’s best turns. The character is best met cold, and Madigan makes every minute of screen time count.

Where Weapons falls short

The chapter structure that makes the first hour so gripping also has a cost. Each new point of view has to replay part of what we have already seen, and by the later chapters the repetition starts to feel more like a mechanism than a revelation. The mystery is at its most powerful while it is unexplained, and the film eventually explains rather more than it needs to. The final stretch trades the slow, quiet dread of the opening for something louder and more conventional. It is entertaining, and the audience Cregger made it for will cheer, but the question the film opens with is bigger than the answer it gives.

None of that stopped Weapons from becoming one of the horror events of its year. It grossed about $270 million worldwide on a budget of around $38 million, drew roughly 93% positive reviews on Rotten Tomatoes and pleased audiences too, if a little less fervently than critics. Beyond Madigan’s Oscar, it won the Critics’ Choice Award for Best Hair and Makeup, and a prequel centred on Gladys is in development.

Where to watch Weapons: HBO Max, Netflix and digital

A New Line Cinema production released by Warner Bros. Pictures, Weapons has been streaming on HBO Max in the United States since October 2025. In Spain it arrives on Netflix on 24 October 2026, just in time for Halloween, after its run on HBO Max. It is also available to buy or rent on the main digital stores. Streaming availability varies by country, so check your local services.

Our verdict is a 7 out of 10: a well-made, original horror film with one great idea and the nerve to build an entire movie around it, even if the ending cannot quite match the opening. Whatever else you forget about Weapons, you will not forget the sight of those children running into the night with their arms spread wide, as if they were playing at being aeroplanes.
