In 1989, Raven-Symoné auditioned for a role in the Bill Cosby movie, "Ghost Dad". At the age of three, she was considered too young for the role, but Cosby liked her so much that he found a role for her on his show, "The Cosby Show", as his step-granddaughter Olivia. She made her debut in the premiere episode of the show's sixth season and remained until the series finale in 1992. She then appeared as the younger version of Halle Berry's starring character, a headstrong biracial slave, in the TV movie "", based on the book by Alex Haley.
