Quentin Tarantino is credited with "presenting" the RZA-directed martial arts action-comedy The Man With the Iron Fists, as if you couldn't tell by the cheeky exploitation tagline, "They Put the F-U in Kung Fu" (which nearly rivals Tarantino's own tagline for Django Unchained). RZA himself stars -- he co-scripted, too -- as a blacksmith in feudal China who gets entangled with a whole lot of unusual fighters, including Russell Crowe's mysterious cowboy and Lucy Liu's fan-wielding know-it-all. (O-Ren Ishii would die for that knife-inlaid fan ... perhaps literally.) There will be a whole lot of R-rated blood and plenty of slow-mo kung fu carnage. RZA! Welcome to the club!
