“Straight Outta Compton,” the film that documents the rise of “gangsta” rap, makes its debut in a new redband trailer, only days after a clash on the movie’s set left one man dead, another injured and rap mogul “Suge” Knight facing murder charges.

The biopic, directed by F. Gary Gray, depicts the rise and fall N.W.A, whose members included Eazy-E, Dr. Dre, Ice Cube, MC Ren and DJ Yella.

The films stars Jason Mitchell (Eazy-E), Corey Hawkins (Dr. Dre), O’Shea Jackson Jr. (Ice Cube), Aldis Hodge (MC Ren) and Neil Brown, Jr. (DJ Yella).

The movie is titled after the group’s debut studio album. It was released in August 1988 and is credited with giving rise to the sub-genre. The music was marked by its profane, violent and misogynistic lyrics.

Even so, it gained rapidly in popularity, launching such acts as Tupak Shakur, Snoop Dogg and Biggie Smalls.

Gangsta rap’s success sparked a feud between East Coast and West Coast rappers that led to the deaths of its two biggest stars, Shakur and Smalls, aka Christopher Wallace.

Knight was implicated although never charged in either murder.

Knight’s company, Death Row Records, went bankrupt in 2006, and he did a stretch in prison for probation violations. Along with a lengthy criminal record, his heavy-handed business dealings left a lot of bad blood in its wake.

Last August, Knight was shot six times outside L.A. club 10AK during a party hosted by R&B singer Chris Brown leading up to the MTV Video Music Awards.

Knight was believed to be the intended target, but refused to cooperate with police.

He was involved in a fatal hit-and-run in Compton today (Jan. 29) following a promotional video shoot for upcoming biopic. He has since been charged with murder and has pleaded not guilty.

According to the official preview, the movie “tells the astonishing story of how these youngsters revolutionized music and pop culture forever the moment they told the world the truth about life in the hood and ignited a cultural war.”

The trailer features an introduction by pioneering rappers Dr. Dre and Ice Cube. It hits theaters in August.
