 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. She was in several Kevin Smith films in that same time period, including a leading role in Mallrats, before landing a lead role on the popular TV show Charmed. Doherty was 53 years old.
