The Villain on “Beverly Hills, 90210”
After four seasons on the show, actress Shannen Doherty left “Beverly Hills, 90210” in 1994. She played Brenda Walsh on the series, but her bad girl reputation followed her in real life and she was fired from the series. “Saved by the Bell” actress Tiffani-Amber Thiessen then joined the cast in season five and her character took over some of Doherty’s storylines.
