The Unauthorized Beverly Hills, 90210 Movie: Which Scenes Really Happened

In her audition in the movie, Shannen has to be reminded that she and Jason Priestley are auditioning for siblings, but hers wasn't the only libido out of control. 

Jason Priestley wrote a memoir as well, the appropriately named Jason Priestley: A Memoir. In it he makes light of all the on-set hookups. He remembers, "There were multiple engagements on the show, with multiple people," but that, "nobody ever got attached. We never let it get in the way what we were doing . . . work always superseded everything."
