An attractive, petite character actress, Wilhoite has worked extensively in theater, film and TV. Known for her portrayals of strong, sassy women, she made her feature debut in the teen-sex comedy "Private School" (1983) and that same year ventured into TV-movies with "Quarterback Princess" (CBS). In addition to supporting Charles Bronson in J Lee Thompson's "Murphy's Law" (1986), she wrote and sang the title song. Wilhoit marked time in small roles in generally forgettable films (Sandra Locke's "Ratboy" 1986; Alan Parker's "Angel Heart" 1987) before landing parts like a college newspaper editor in "Campus Man" (also 1987) and reporter Hank O'Hare in "Brenda Starr" (1989). Other credits include "Lorenzo's Oil" (1992), "Fire in the Sky" (1993) and "Color of Night" (1994).
Television has provided Wilhoite with some of her best roles. She has made guest appearances on such shows as "Cagney and Lacey" and "Cop Rock", in which she had a recurring role as a drug-addicted mother. Her TV-movies include "Single Bars, Single Women" (ABC, 1984), "Not My Kid" (CBS, 1985) and "Broken Promises: Taking Emily Back" (CBS, 1993). Wilhoite was chosen by cartoonist Cathy Guisewite to provide the voice of "Cathy" in several animated specials based on the popular comic strip. She has also portrayed the mentally challenged girlfriend of Larry Drake on the NBC legal drama "L.A. Law" (NBC, 1993-94) and is remembered as the child-like Chloe, whose pregnancy and childbirth caused difficulties for her doctor sister (Sherry Stringfield) on "ER".
