Reports suggest King's family have passed Paul Webb's screenplay to lawyers in a bid to halt any film from portraying the people's hero as a cheater, who enjoyed the company of prostitutes and mistresses.
But Daniels, who is making the biopic Selma with Brad Pitt as producer, insists the Kings have nothing to fear.
He explains, "The script they have is not my script. This project is still in an embryonic stage, but I can tell you my story focuses on the civil rights marches. It’s not about tapes and prostitutes. It’s about the African-American man who changed history."
