When a kickboxing police inspector is murdered, his kickboxing twin brother infiltrates the Russian mob in order to see justice meted out--as painfully as possible. A slimmed-down Jean-Claude Van Damme is surprisingly effective as the lead(s), but the real star here is gritty Hong Kong director Ringo Lam (probably best known for City on Fire, the film that inspired Quentin Tarantino's Reservoir Dogs), who makes a lethal American debut with this hard-edged, convoluted film, which uses the identical-sibling gimmick to considerably darker effect than the goofball Double Impact. Some incredible stunt work and a terrifically ruthless final reel make this underrated action film a winner, although fans of Species may be somewhat disappointed that costar Natasha Henstridge never fully displays the assets that made her famous. --Andrew Wright
