Gibb's real breakthrough was the starring part in the TV-movie "The Karen Carpenter Story" (CBS, 1989). She's worked steadily though a successful series has thus far eluded her. Gibb has graced such pilots as "When We Were Young" (NBC, 1989) and "Midnight Caller" (NBC, 1990), and has been a regular on the short-lived series "Madman of the People" (CBS, 1994-95) and "Deadly Games" (UPN, 1995-96).
TV-movies have continued to provide Gibb with good roles and steady employment. She appeared with Dick Van Dyke in three CBS Dr. Sloan mysteries ("Diagnosis of Murder" and "The House on Sycamore Street", both 1992, and "A Twist of the Knife", 1993), and supported Roseanne and Tom Arnold in "The Woman Who Loved Elvis" (ABC, 1993). She also co-starred in "Sin and Redemption" and "Fatal Vows: The Alexandra O'Hara Story" (both CBS, 1994). Gibb's most prominent role to date was the title role opposite Bette Midler's Mama Rose in the TV version of the hit Broadway show "Gypsy" (CBS, 1993).
