Moira Kelly played Mandy Hampton on the first season of The West Wing. She left the show after the first season after producer Aaron Sorkin decided that her character had played its story out and that Janel Moloney served as a better foil for Bradley Whitford. Her character was not mentioned on the show again, leading to the term Mandyville.
Kelly also had a starring role on One Tree Hill and is perhaps best known as the voice of Nala in the Lion King series of movies. She also starred in the motion pictures Chaplin, Twin Peaks: Fire Walk With Me, With Honors and The Cutting Edge.
