When a rapper-cum-actor-cum-author-cum-producer decides to turn director, either he is really multi-talented, or he is on drugs. With RZA, it is a little bit of both, as you will find out when you watch his directorial debut, The Man With The Iron Fists.
One look at the poster or at the promos, and you will think this is a Quentin Tarantino film - RZA scored the music for Kill Bill, and one guesses that he was heavily influenced and impressed by Tarantino's style, because that is when the germ of the idea (for this film) first entered his head.
