“Devil in a Blue Dress” director Carl Franklin has replaced John Singleton as director of Morgan Creek’s “Tupac,” the long-in-development biopic about rapper Tupac Shakur, with casting under way.

Shooting is planned to begin in August or September, according to Morgan Creek spokesman Greg Mielcarz. Singleton left the project over creative differences several months ago, Mielcarz told Variety.

For his part, Singleton said on his Instagram account this week, “The reason I am not making this picture is because the people involved aren’t really respectful of the legacy of Tupac Amaru Shakur.”

Singleton had fallen off the project in 2012 and come back on in 2014.

“Tupac,” written by Jeremy Haft and Ed Gonzalez, will follow the rise of one of the most popular hip-hop artists and his 1996 murder following a boxing match in Las Vegas.

Franklin’s directing credits include episodes of “The Newsroom,” “House of Cards,” “Homeland” and “The Affair.”

Mielcarz said Wednesday there are no legal issues with the film. Morgan Creek sued Shakur’s mother, Afeni, in 2009 after she demanded approval over the direction of the project. The parties reached a settlement over the rights in 2011, which provided that she become an executive producer on “Tupac.”

Franklin is repped by Paradigm and Anonymous Content. Haft and Gonzalez are repped by Luber Roklin and Summitt Talent & Literary Agency.
