Tupac Shakur's forthcoming biopic, "Tupac," has experienced a slight shift as it was announced last week that “Devil In A Blue Dress” director Carl Franklin has been named to replace John Singleton as the film's director.

According to Variety, the film’s spokesman, Greg Mielcarz, stated Singleton departed from the much-anticipated project -– after exiting in 2012 and returning in 2014 –- due to creative differences. Following the announcement the Academy Award-nominated director took to his Instagram accountto explain why he’s walking away from the developing film for the second time in three years.

Real talk! The reason I am not making this picture is because the people involved aren't really respectful of the legacy of Tupac Amaru Shakur. I won't say much if you want you can read my articles in Hollywood Reporter on authenticity in Black Storytelling ... To Pac's real fans just know I am still planning a movie on Tupac ... It doesn't matter what they do mines will be better... 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... Real talk! How you gonna make a movie about a man when you suing his mother to get the rights to tell his story?! They have no true love 4 Pac so this movie will not be made with love! And that's why my ass isn't involved ! If Tupac knew what was going on he'd ride on all these fools and take it to the streets... But I won't do that ... I'll just make my own project. What Yall think about that?!!

Singleton worked with the late rapper for his 1993 film “Poetic Justice.” During a 2013 interview with Essence, which also commemorated the film’s 20th anniversary, Singleton recalled his fondest memories of Shakur, including his intentions to cast him for the lead role in 2001's “Baby Boy” which was later fulfilled by actor Tyrese Gibson.

“People always idolize 'Pac, but he was really just a brilliant yet confused young kid with a lot of fame,” he told Essence. “He had nothing to ground him, no father. He had no one to tell him ‘no’ or ‘just sit down.’ But when you did tell him something, he’d respect you. Right before he passed we just started talking again.”

“I saw him a week an a half before he went to Las Vegas and I told him I’m working on a new movie [Baby Boy, 2001] and I told him that this will be the movie that will get him an Oscar. He said, ‘Anything you want I’m there.’ He was going to be my Robert DeNiro. We were going to grow together. When you see Baby Boy now, his presence and soul are still in that movie.”

Casting for “Tupac” is set to begin in the coming months, with filming beginning later this year.
