In “Inside Men,” a smashing political revenge thriller with more double-crossings than “Infernal Affairs,” a prosecutor allies himself with a gangster to topple the corrupt cabal formed by a congressman, a tycoon and a media pundit. South Korean writer-director Woo Min-ho (“The Spies”) has crafted a deliberately paced yarn packed with shrewd political insight and gripping procedural detail. An instant domestic hit, the film enjoyed a second wind when a three-hour director’s cut was released a month later, pushing its B.O. total to about $62.95 million. It should be no outsider to major Asian markets and genre circles.
