Carl Franklin has stepped in as director of Morgan Creek?s long-gestating, untitled biopic about Tupac Shakur in the wake of the departure of John Singleton from the project. Singleton posted a message on his Instagram account Tuesday, confirming he is no longer involved with the film. Singleton wrote, ?The reason I am not making this picture is because the people involved aren't really respectful of the legacy of Tupac Amaru Shakur." He also added, ?Tupac was much more than a hip hop artist ... He was a black man guided by his passions ... Of most importance was his love of black people and culture ... Something the people involved in this movie know nothing about."??
