Oliver Stone has revealed that he is no longer involved with directing and writing a biopic about Dr. Martin Luther King Jr.

The director tweeted about the news yesterday (January 17), saying that the producers had rejected his script.

He wrote: "Sad news. My MLK project involvement has ended. I did an extensive rewrite of the script, but the producers won’t go with it.

"The script dealt w/ issues of adultery, conflicts within the movement, and King’s spiritual transformation into a higher, more radical being.

"I’m told the estate & the ‘respectable’ black community that guard King’s reputation won't approve it. They suffocate the man & the truth.

"I wish you could see the film I would've made. I fear if ‘they’ ever make it, it’ll be just another commemoration of the March on Washington."

He added: "Martin, I grieve for you. You are still a great inspiration for your fellow Americans—but, thank God, not a saint."

Jamie Foxx has been linked to the project, which is a co-production between Warner Bros and DreamWorks.
