Movies like The Beekeeper

If you want The Beekeeper's blend of methodical vengeance against systemic corruption, you'll likely connect with Ruthless or Beyond the Mask—both track a skilled operative's escalating war against institutional evil that expands far beyond the initial target. Cape Fear and The Suspect may scratch a similar itch for the cat-and-mouse psychological tension and conspiracy-unraveling, though they're less focused on the protagonist's righteous fury driving the violence. Blood Honey probably comes closest to the intimate knowledge-as-weapon dynamic, where a wronged insider dismantles corruption from within their antagonist's world.
