Movies like Nobody

If you're after that specific tension of an ordinary man's violent capabilities erupting when his carefully ordered suburban life gets threatened, you'll likely find similar ground in A History of Violence or The Strangers—both mine that same claustrophobic dread of home invasion and moral compromise, though they lean harder into survival horror than the measured escalation Nobody pulls off. The slow-burn psychological unraveling in Enemy or Inside Out (2005) might scratch a different itch if you're more interested in the psychological collapse beneath the violence than the violence itself. Most of these options trade Nobody's pulpy revenge momentum for either paranoia-driven tension or the moral weight of a man confronting what he's become, so your mileage depends on whether you want that same pace or just the theme of repression exploding.
