Was half of a singing duo with Michael Dunn. The producers of James West (1965) saw them perform, and tapped them to play Dr. Miguelito Loveless and his companion Antoinette. When Dunn later married, his new wife was jealous of Dorin, and made Dunn break up the act. Dorin also no longer appeared as Antoinette; Loveless was given other companions in later episodes.
