Tina Turner

Black women artists like Josephine Baker, Nina Simone and Eartha Kitt contributed to those social gains. Their suffering came not only from their personal battles against day-to-day racism in America, but also having their careers struggle when they spoke out against it. Europe eventually became home to them as well.

Near the end of HBO's new documentary, Tina, the movie implies the legendary singer has made a decision: after this film rolls out, Tina Turner just might be done appearing in public and talking about her life. It's an odd message, coming from a woman whose life story and experiences have inspired at least four books, an Oscar-nominated biopic, a Broadway musical and, now, this new film.

Tina playwright Katori Hall and star Adrienne Warren have plenty to say about working with the star, depicting domestic violence and learning to sing in a new voice.
