Shannen Doherty had more than her fair share of harmful career setbacks because she didn't always play nice. While that sounds unreasonable nowadays, Doherty's behavior was rumored to have gotten her fired from the two TV shows that made her a star ... "Beverly Hills, 90210" and "Charmed." It's unclear if Doherty was ever actually terminated from either series, but it appears she at least felt pushed out and left on bad terms.
Regarding Doherty's "Beverly Hills, 90210" departure, she admitted to EW that she was miserable and didn't want to be on set. The show's creator, Aaron Spelling, however, claimed that she constantly distressed her co-stars. "She thought it was time to go. And the cast did too," he explained. Spelling's daughter and Doherty's co-star, Tori Spelling, blamed herself for Doherty's firing because she had complained to her dad about Doherty. She recalled on "Celebrity Lie Detector" (via Distractify), "I felt like I was a part of something ... a movement ... that cost someone their livelihood."
Things weren't much better on the set of her next major show, "Charmed," because Doherty reportedly didn't get along with her co-star, Alyssa Milano, there. According to TV Guide, the actors started out friendly but eventually had a falling out that apparently resulted in feelings that one of them had to leave the series. That turned out to again be Doherty, who later told ET, "There was too much drama on the set and not enough passion for the work."
