Russell Crowe and Wu Tang Clan leader RZA are joining forces again on new kung fu film The Man With The Iron Fist. The action film will be co-written and directed by the rapper-producer, who previously appeared with Crowe in 2007's American Gangster. Talking with Eonline.com, the RZA explained: "Russell's going to be the baddest man alive. That man is in fighting shape. That man will knock you out. It's nerve-wracking. [Crowe's] a master of the craft.
