The new signees join Jennifer Hudson in the lead (reportedly, hand-picked for the role by The Queen of Soul herself.) Due on August 14th, 2020, production on Respect began this month after an open call audition for an actress to portray Franklin as a child. Broadway actress Skye Dakota Turner, was offered the role.

Franklin's story will also be on small screens in the months ahead. Last month, Cynthia Erivo signed on to portray the singer in Genius Aretha, an upcoming scripted series for National Geographic. That project is expected to premiere in Spring 2020.
