This is not really a classic movie question but it is a question about a big screen movie from the 80's that featured a Black Character Actress from the 50's or 60's.
The movie was about a Black Character actress who had a successful, but "second-class career" in Hollywood. She played a maid or household manager in a TV show and was a strict disciplinarian, often being quite abusive with her older daughters at home. It had shades of the Ruby and Dorothy Dandridge story with Geneva Williams being cruel to Dorothy.
Does anyone know the name of the 80's movie?
