The Belko Experiment
An office tower gets locked down and a voice over the intercom starts ordering employees to kill each other or be killed. It's Lord of the Flies with lanyards — a pitch-black satire on workplace hierarchy and how quickly civility dissolves. James Gunn's script keeps it lean and mean at 89 minutes: gory, propulsive, occasionally very funny, and never pretending to be more than a nasty office party gone wrong.

Battle Royale2000
The original blueprint for 'ordinary people forced to murder each other' — a school trip turned death match that's brutal, stylish, and surprisingly tender about the kids caught inside it.
But Subtitled and unapologetically savage with teenagers as victims, which some viewers find much harder to sit with than office workers.

The Purge2013
Sanctioned violence as social experiment, just at the scale of a whole country instead of one office — same nasty thesis about what people do when the rules disappear.
But The home-invasion plotting is thinner than Belko's ensemble chaos, and the satire is broader, less clever.

Cube1998
Strangers trapped in a shifting geometric prison, forced to cooperate or turn on each other to survive — the low-budget, high-concept ancestor of every 'trapped and tested' thriller since.
But Slower and stagier than Belko, with dated effects and dialogue that leans hard into philosophical monologuing.

The wildcard
Something you would not have found on your own.
Lord of the Flies1963
Belko is literally this book restaged in a skyscraper — ordinary people, stripped of institutional rules, left to invent a new and brutal order among themselves.
The original text on what happens when authority vanishes and people are left to govern themselves — cold, matter-of-fact, and more chilling for how plausible it feels.
But Black-and-white, 1963, no gore and no jokes — it's a somber literary adaptation, not a thriller with jump scares.

Would You Rather2013no page yet
A dinner party turns into an escalating game of cruelty for cash — smaller and cheaper than Belko, but the same queasy math of what desperate people will do to each other.
But Low-budget seams show throughout, and the ensemble cast is a fraction as fun and starry as Belko's.
Circle2015no page yet
Fifty strangers stand in a dark room, and every two minutes someone votes another to die — a tighter, talkier, more claustrophobic riff on the same premise.
But No action, no gore, just people arguing in a circle — a very different, much slower kind of tension.
The Hunt2020
Rich elites hunting ordinary people for sport, dressed up as vicious political satire aimed squarely at America's divides — same instinct to turn moral panic into splatter comedy.
But The politics are loud and try-hard in a way that dates it fast, and the satire lands less cleanly than Belko's.

Mayhem2017no page yet
An office building gets quarantined by a virus and everyone's worst impulses go feral — practically Belko's twin, right down to the corporate setting and gleeful bloodletting.
But Rougher production values overall, and a scrappier, rowdier sense of humor than Belko's slicker studio polish.
Gamer2009no page yet
Death games controlled by an unseen authority, except here it's death row inmates puppeted by teenagers online — same rigged-system dread with a neon, video-game sheen.
But Gerard Butler's growl-and-punch routine and Neveldine/Taylor's hyperactive editing are a lot to take if you want something more grounded.
You're Next2013
A home invasion where the supposed victim turns out terrifyingly capable — less about a rigged system, more about one person refusing to play the victim role.
But The ensemble-versus-system premise is gone; this is a slasher with one breakout survivor, not group dynamics under pressure.

Quiet Rage: The Stanford Prison Experiment1992no page yet
This is the real event behind the idea Belko dramatizes — ordinary volunteers handed power over each other and turning cruel within days, no supernatural voice required.
Actual footage of the notorious 1971 Stanford Prison Experiment spiraling out of control within days — the real-life proof that Belko's premise isn't really science fiction at all.
But No plot, no stars, no catharsis — it's a grainy academic document, and it's more troubling for being real.
Compliance2012
Same core mechanism as Belko — an unseen voice giving orders that ordinary employees obey further than they should — but stripped of guns, gore, and any release.
A fast-food manager follows a caller's instructions further than seems possible, and the film never blinks — a devastating, true-story cousin to Belko's premise without a drop of blood.
But It's quiet, humiliating, and based on a real case — there's no splatter catharsis here, just a slow-burn sense of dread.
