Ice Cube premieres the movie trailer for N.W.A.’s biopic Straight Outta Compton.

The films chronicles the story of one of the most famous rap groups in history N.W.A. which rose to fame in the 1990s with Dr. Dre, Eazy-E and Ice Cube, who grew up in Compton.

The bootleg version of the action packed trailer surfaced on YouTube yesterday.

“Let me tell you what I see here: A lot of raw talent, swagger, bravado. People are scared of you guys,” actor Paul Giamatti said in the trailer. He stars in the film as N.W.A.’s manager Jerry Heller.

The film is directed by F. Gary Gray and saw Jason Mitchell as Eazy-E, Corey Hawkins as Dr. Dre, and O’Shea Jackson Jr., who is Ice Cube’s son playing his dad.

Straight Outta Compton premieres in theaters on August 14, 2015.
