Movies like Bullet Train

If you want that claustrophobic pressure-cooker vibe where incompatible agendas collide in a confined space with escalating chaos, you'll likely connect with Train to Busan or Murder on the Orient Express—both trap multiple characters with conflicting motivations in an inescapable setting, though the former leans harder into kinetic action while the latter favors puzzle-box mystery. For the specific blend of absurdist dark humor erupting from operatives forced into close quarters, Baby Assassins probably comes closest to matching that tone, assuming you care less about the train setting itself and more about incompatible people creating mayhem through proximity.
