Entertainment Weekly confirmed MGM has acquired the rights to the biopic. Straight Outta Compton producer Scott Berstein and Dreamgirls music arranger Harvey Mason will produce the film.
The new movie is reportedly based on Franklin's memoir, Aretha: From These Roots. The singer told People in 2016 that she had spoken to the actress who will play her in the film, although she didn't share the person's name.
"I'm not going to say who I chose, but I've talked to her and she's ready and I'm happy with her," she said.
