Christian Bale played Grammaton Cleric First Class John Preston, an elite lawman in a dystopian, post-apocalyptic society. Equilibrium featured a fictional martial art style called Gun Kata, developed by Kurt Wimmer (writer and director). Equilibrium didn't do well at the cinemas but became a cult classic. Gun Kata was featured again in UltraViolet (2006) - written and directed by Wimmer, starring Milla Jovovich as Violet fighting in a (surprise! surprise!) dystopian, post-apocalyptic society.
