Rapper 50 Cent has hit back at Samuel L Jackson's claims he turned down a role in his forthcoming movie, by asserting the Pulp Fiction actor would only have been cast as a "crackhead" anyway. Former crack dealer 50 Cent makes his film debut in the semi-autobiographical "Get rich or die tryin'". He tells the New York Daily News: "I don't even see where Samuel fits into my life story anyway, unless he plays one of the crackheads. He was a crackhead originally, right? "So I come from being a rapper, and he comes from being a crackhead."
