The actors re-recorded NWA's entire Straight Outta Compton album (with producer Harvey Mason Jr.) to help them get into character.
The letter that the FBI sent to NWA can be seen at The Rock and Roll Hall of Fame in Cleveland, Ohio.
The original cut of the film was 3 hours and 30 minutes. The cut scenes included Dr. Dre's infamous beating of journalist Dee Barnes, the incident where Dre was shot four times in the leg, and a graphic flashback of his younger brother's death.
When Ice Cube is complaining to Bryan about not yet having received his money, he exclaims that he has a baby on the way. Cube was in fact talking about O'Shea Jackson Jr., who was his first born in 1991. (Meaning that O'Shea Jr was talking about himself during this scene.)
Eazy-E and MC Ren were the only members of NWA who belonged to a street gang. They were both members of the Kelly Park Compton Crips, a Crips sect in the Kelly Park neighbourhood of Compton. They were friends long before NWA was formed and they gangbanged and sold drugs together before venturing into music.
F. Gary Gray: as Greg Mack, the DJ that plays Eazy-E's record. Greg Mack was the host of the Mack Attack on KDAY, one of the first radio stations to play hip-hop 24/7.
