Campbell moved to Los Angeles and landed the role of a rich girl who was mistakenly behind bars on "Women in Prison" (Fox, 1988), her first sitcom. She returned to daytime with a regular role on the NBC soap "Santa Barbara" (1988). The following year, it was back to primetime in the summer comedy "Knight & Daye" (NBC, 1989). After making guest shots, Campbell had the recurring role of the hero's girlfriend in "Herman's Head" (Fox, 1991), was a beautician infatuated with Robert Hays on "Cutters" (CBS, 1993), and the savvy 90s woman partnered with two fledglings in "Blue Skies" (ABC, 1993). When the latter failed, the network put her in "A Whole New Ballgame" as leading lady to Corbin Bernsen, but that too flopped. Hoping for some stability, she signed on as Cherie, the neighbor to the "Men Behaving Badly" (NBC, 1996), but left soon after the series began airing.
Her feature career has been slow to start. She debuted in "Body Count" (1988), and was leading lady to Dana Carvey in the misfire "Opportunity Knocks" (1990). More recently, Campbell was Christy, the bitchily acidic nemesis to Lisa Kudrow and Mira Sorvino, in "Romy and Michele's High School Reunion" (1997).
