 Members of N.W.A were involved in making the film, including Ice Cube and Dr. Dre as producers, as was Eazy-E's widow, Tomica Woods-Wright, while MC Ren and DJ Yella served as creative consultants.

 Born in Compton, California, he released his first mixtape "You Know What It Is Vol.
 1" in 2002; shortly after, he was signed to Dr. Dre's Aftermath Entertainment label.

Gylan Kain is an American poet and playwright.
 He is a founding member, in 1968, of the Original Last Poets (along with Felipe Luciano and David Nelson).
 He is known for creating the aggressive, rhythmic delivery of spoken word aka performance poetry as it is known today.
 He often performs with hand drums or backing musicians such as saxophonists and bass guitarists.
 His work has often been sampled without pre-consent by well-known artists including Dr. Dre and The Prodigy.
 One of his performances was sampled into the club hit "Voodoo People" by The Prodigy.
 Dr. Dre sampled an excerpt of Kain performing his poem, "The Shalimar" on Dre's track entitled "Intro" from the album entitled "The Chronic."
 After legal action was successfully taken to procure compensation for work sampled by The Prodigy, spokespersons for The Prodigy claimed that efforts had been made to procure permission from Kain for use of his work but those efforts had been unsuccessful because Kain, who values privacy, could not be located in time.
 Dr. Dre has yet to compensate Kain for work sampled without prior consent.
 This has led some fans to criticize Dr. Dre as an hypocrite for exploiting the work of an influential Black artist after building a reputation as an empowering force in the black American community as a founding member of N.W.A.
"Express Yourself" is a song recorded by American hip hop group N.W.A, performed solo by Dr. Dre.
