Shelley's last movie (theatrical release) to date, is House Arrest, 1996. Directed by her husband Harry Winer, the movie starred Jamie Lee Curtis, Kevin Pollak, Jennifer Love Hewitt, Jennifer Tilly, to name a few.
Also in the cast is Shelley and Harry's daughter Rosie Winer (as she is credited) who played a flower girl in the flashback scene in the movie.
Shelley is uncredited in the film but her character actually has a name. She is Dr. Erica Gilliland, Ph.D., writer of the book Feel The Fear And Go For It. Dr. Gilliland only appears on a TV screen and on the back cover of her book. Shelley's appearance in the film is short but delightful.
