Last April's open casting call by F. Gary Grey, the director of the upcoming N.W.A. biopic "Straight Outta Compton" has finally had its results announced. The purpose of this casting call was to look for the right actors to play the main characters in the movie.

Grey said that he is actively looking for someone who has the "hood" factor to make for an authentic presentation of the origins of the hip-hop group.

He has now filled three main roles of the film, said The Hollywood Reporter. O'Shea Jackson Jr., the son of Ice Cube, is being cast as his father. Joining him are Jason Mitchell as Eazy-E and Marcus Callender as Dr. Dre. Michael B. Jordan was Dre's preferred choice to play his younger self, but Jordan was not available due to his lead role in the upcoming "Fantastic Four" film.

Callender, a trained actor from New York's Shakespeare Lab at the Public Theater, was in HBO's "Criminal Justice" and CBS's "Blue Bloods" as well as "Elementary." Mitchell has previously appeared in "Contraband" and "Broken City." Dr. Dre, Ice Cube, and Tomica Wright (widow of the late Eazy-E) have all agreed to the choice of actors. They each have the power to veto both actors and scripts for the project, which has reportedly contributed to the several year-long time frame it has taken for the project to reach this point.

The project has been in talks since being announced by Grey back in 2009. He was quoted in Rolling Stone as saying "It's not unlike Social Network or American Graffiti where you take a place and time in America, especially as it relates to popular culture, and you see the shift, and they were right there and created part of the pivot that America took in entertainment."

The film's principal photography will start in less than two months' time. This far out, it is still unknown when the film will be released.
