Career
Arguably, she is best known for her performance as the seductive, swinging housewife Elvira in the Radley Metzger film Score (1973). She played Elvira for 23 performances from October 28 to November 15, 1970, at the Martinique Theatre in New York City, and was the sole performer to make the transition from the stage play to the film. After Score, Wilbur appeared in the sexploitation film Teenage Hitchhikers.
In later years, she worked as a dedicated animal rights activist and wrote two unpublished books of verse about the Mankei Neko, a porcelain Japanese feline commonly known as "The Beckoning Cat": Mankei Neko: The Japanese Legend Of The Beckoning Cat and The Japanese Legend of the Cat and the Crone.
Wilbur was diagnosed with lung cancer in 2003 and died peacefully in her Upper East Side apartment in Manhattan on May 20, 2004.
