The Beverly Hills, 90210 set was no stranger to behind-the-scenes drama, especially when Shannen Doherty (Brenda Walsh) was involved. Her strong personality often clashed with Jennie Garth (Kelly Taylor) and Tori Spelling. Things got so tense that, according to Spelling, she asked her producer father to write Doherty off the show. There’s even talk of a physical fight between Doherty and Garth — the kind of gossip that still gets mentioned when 90s TV is discussed.
