Shannen Doherty feuded with so many of her "Beverly Hills, 90210" co-stars that producer Aaron Spelling removed her from the cast at end of the fourth season (in March 1994). (Using digital effects, producers even removed her entirely from the series retrospective, an hour long special which featured virtually every other actor in show's history.)

Doherty and Jennie Garth "competed over wardrobe, over everything," Joe E. Tata once recalled. Indeed, they once held up a photo shoot because they were battling over a certain red dress. Jason Priestley once turned beet red, grabbed Doherty by the neck, and wrestled her to the ground (after she snuck into his dressing room, found his driver's license, and announced his age). And Luke Perry? "Luke," Doherty herself recalled, "once threw a tray of food at me!"
