LOS ANGELES — Academy Award-winner Steve McQueen is set to direct a documentary about Tupac Shakur. Shakur Estate trustee Tom Whalley and Amaru Entertainment said Tuesday that the film is fully sanctioned by the late hip-hop artist’s estate. McQueen is best known for directing “12 Years a Slave,” which won the best picture Oscar in 2014 and earned him a best director nomination. The director said in a statement that he looks forward to working with Shakur’s family to bring his unvarnished story to life.
