The star, who was award-nominated for her role in Dreamgirls, is also set to be an executive producer on Cadillac Records, says the Hollywood Reporter.
Adrien Brody, who won a best actor Oscar for his performance in The Pianist, will also star in the movie.
Blues star James scored her UK hit in 1996 on the back of a Diet Coke advert.
Cadillac Records deals with Chicago-based record label Chess and the turbulent lives of some of its star recording artists, including Muddy Waters and Chuck Berry.

Beyonce will record four songs for the film's soundtrack, the report added.
She will reportedly donate a portion of her fees to the Survivor Foundation, a charity which helps recovering drug addicts.
The singer, whose film credits also include Austin Powers in Goldmember, was nominated for a Golden Globe for her role in musical film Dreamgirls, while the soundtrack gained a Grammy Awards nod this year.
Beyonce's Irreplaceable, from her album B'Day, was also nominated for record of the year at the ceremony, where the star performed a duet with Tina Turner.
