Movies like The Long Walk

You're likely to find similar ground in Squid Game and The 100—both share that relentless elimination structure and explore how desperation transforms ordinary people into competitors willing to endure impossible trials, though Squid Game leans harder into the psychological degradation while The 100 adds the state apparatus angle. If you want the pure physical endurance + mounting dread combo, Cub and A Few Steps Further probably nail it best, trapping protagonists in hostile landscapes where the ordeal itself becomes the antagonist rather than any single threat. The Walking Dead might feel closest in pacing and tone—that constant navigation through a hostile world filled with moral compromise—but it's sprawling where The Long Walk is claustrophobic.
