===Departures===
The departure of Shannen Doherty at the end of season 4 came after a period of strife between Doherty, the other cast members, and the show's producers. Executive producer Charles Rosin commented in 2000 that Doherty "had habitual lateness, her lateness was appalling, and she had a callous attitude and an indifference."<ref>{{Cite magazine |last=Shaw, Jessica |date=May 19, 2000 |title=''90210''{{'s}} last episode aired May 17 |url=https://ew.com/article/2000/05/19/90210s-last-episode-aired-may-17th/ |magazine=Entertainment Weekly |access-date=July 22, 2017}}</ref> Trouble between Doherty and her co-stars, Jennie Garth in particular, was also widely reported in the media.<ref name=":1" /><ref name="Associated Press">{{Cite news |date=August 27, 2008 |title=Jennie Garth, Shannen Doherty Make Nice While Filming New '90210' |publisher=[[Associated Press]] |url=https://www.foxnews.com/story/jennie-garth-shannen-doherty-make-nice-while-filming-new-90210 |access-date=August 7, 2019 |via=[[Fox News]]}}</ref><ref>{{Cite web |date=November 6, 2010 |title=The View (November 4, 2010) |url=https://www.youtube.com/watch?v=vO_N7UoXPiQ |url-status=live |archive-url=https://web.archive.org/web/20200309034916/https://www.youtube.com/watch?v=vO_N7UoXPiQ&gl=US&hl=en |archive-date=March 9, 2020 |access-date=July 22, 2017 |website=[[YouTube]] }}</ref> Doherty, who was struggling in her personal life with her father's illness, came to an agreement with the producers to phase her out of the show at the beginning of season 4, when Brenda returns to Minnesota for college. It was planned to reduce her appearances from that point, but Doherty had a change of heart and requested to remain as a main cast member.<ref>{{Cite AV media |title=Beverly Hills, 90210 Season 4: A Look Back with Charles Rosin |type=dvd |publisher=Paramount DVD |year=2008}}</ref> However, as the fourth season wore on Doherty's attitude deteriorated and her friction with the other cast members intensified. When she caused continuity problems by cutting her hair halfway through filming an episode, the producers and cast requested from Aaron Spelling that she be fired.<ref name="EW">{{Cite news |last=Kickham |first=Dylan |date=October 4, 2015 |title=12 things you never knew about 'Beverly Hills, 90210' |publisher=Entertainment Weekly |url=https://ew.com/article/2015/10/04/beverly-hills-90210-things-you-never-knew/ |access-date=August 6, 2019}}</ref>

In season 5, the production accommodated Gabrielle Carteris' pregnancy by reluctantly writing a pregnancy storyline for Andrea. The producers were unhappy with the more adult direction of the character, and Carteris was written off the show at the end of the season.<ref name="EW" /><ref name="Rosin">{{Cite news |date=January 17, 2010 |title=Exclusive: Beverly Hills 90210 Producer Talks College Years, Slams New 90210 |url=https://teendramawhore.com/2010/01/17/beverly-hills-90210-producer-talks-college-years-slams-new-90210/ |access-date=August 6, 2019}}</ref> Also in season 5, [[Jamie Walters]] was introduced as Donna's boyfriend Ray, who later begins abusing her. The writers intended to "rehabilitate" the character in season 6, and Walters signed a $1 million contract. However, the show received such a flood of negative mail from fans complaining about Donna being "stupid" for staying with her abuser, that an angry Aaron Spelling ordered that Walters should be fired. Producer Larry Mollin said of the incident that "he [Walters] got to walk away with his money. But it was still devastating for him. We left him as being a beater, which stayed with him, unfortunately. People thought he was a beater. It was just terrible."<ref name="Rosin" />
In Season 9 Jason Priestley left the show after starring in 4 episodes.
