 Shannon Doherty became an instant celebrity when she burst onto the scene as Brenda Walsh on Aaron Spelling's huge hit, Beverly Hills 90210. The Memphis, Tennessee-born actress began her career in television at the age of 11 in small roles. Then, in 1988, she hit the big screen in the dark comedy, Heathers. She left her role as Brenda on 90210 in 1994. Doherty followed that with primarily made-for-TV movies, though.
