This perky, wholesome actress has found more success in TV-movies and series than in feature films. The New Englander began modeling and doing bit parts in high school (including her film debut in Woody Allen's "Stardust Memories," 1980). Upon graduation, Gibb landed a role as a scatter-brained teen in "Search for Tomorrow" (CBS, then NBC 1981-83), which led directly to another teen role, an ambitious WASP in "Fame" (syndicated, 1983-86). Gibb entered films in 1986, playing three roles that year: in the Rob Lowe starrer "Youngblood," as a Catholic woman raped and murdered by the death squads in Oliver Stone's "Salvador" and in the teen comedy "Modern Girls." She generally has exhibited intelligence and ability in rather unremarkable films, including "Malone" (1987), "Jack's Back" (1988), "Short Circuit 2" (1988) and "Death Warrant" (1990).
