It stars James McAvoy (Atonement) as a pathetic office drone who gets enlightened into becoming a sort of super assassin. Angelina Jolie (looking great as always) and Morgan Freeman turn in their usual high caliber work as his gurus. And Chris Pratt (Bright from Everwood) and Terrance Stamp (Zod from Superman II) have notable minor roles.
I've never seen any of director Timur Bekmambetov's other films, although I've heard very good things about the Nightwatch movies. The guy can sure do some killer, giddyifying action sequences.
