7. Shannen Doherty's Attitude Got Her Fired - Beverly Hills, 90210
While Beverly Hills, 90210 was one of the most popular shows of its time, it was also a series that was often a tense affair behind the scenes. Front and centre amongst this was Shannen Doherty.
Playing Brenda in the show, there are numerous recollections from various different cast members that Doherty was a nightmare to work with. There were arguments, there was an attitude problem, and there was even a physical fight with co-star Jennie Garth.
As an act of revenge - and one of that sounds fully justified, to be fair - fellow co-star Tori Spelling got Doherty fired. One day Shannen was on the set, the next day she was gone, with her character of Brenda disappearing during the fourth season of Beverly Hills, 90210.
How did Spelling have the power to pull this revenge play? Why, that would be because her father Aaron was the producer behind 90210. By speaking to her old man, that meant the axe swung on Shannen Doherty's time on one of the hottest shows of the '90s.
Subsequently, Aaron Spelling would give Doherty another shot by hiring her for Charmed years later. Again though, after rumours of troublesome on-set behaviour, Shannen's Charmed character of Prue Halliwell was killed off at the close of the show's third season.
