It's been rumoured and talked about for some time, but now at long last, the N.W.A. biopic is a reality and even has a trailer.

Straight Outta Compton tells the often-bizarre and controversial rise of rap's most dangerous group, N.W.A.

Made with the participation and full support of both Dr. Dre and Ice Cube - they appear in a little montage beforehand - Straight Outta Compton looks like it has the ingredients to become a classic music film.

What's more, Cube's own son, O'Shea Jackson Jr., will play his dad whilst the always reliable Paul Giamatti will play their manager Jerry Heller.

Directed by F. Gary Gray, Straight Outta Compton hits Irish cinemas on August 14th.
