Rap superstar 50 Cent, aka Curtis Jackson, takes a page from the Eminem playbook, making his movie debut in a largely autobiographical drama presided over by an A-list director–in this case Jim Sheridan (My Left Foot, In America). Like Jackson in real life, the hero of this gangsta melodrama becomes a drug dealer after his mother dies, sustains nine bullet wounds in a street shooting, and turns his life around to become a multiplatinum recording artist. Sheridan gives this a pacing and depth one doesn’t often find in “urban” product, though Jackson, reliving his own life traumas, is handily upstaged at every turn by Terrence Howard (Crash) as his oddball manager.
