Dame Helen Mirren plays a princess in the classic fairy tale story. Shelley Duvall is host and executive producer of the series which aired on cable television in the eighties. Shelley has been having a rough time in the last few years. This episode has a star studded cast with Pam Dawber as Pearl, the little mermaid who lives under the sea with her father, King Neptune played by Brian Dennehy. Pearl has two sisters played by Laraine Newman and Donna McKechnie. Karen Black played the sea witch. Treat Williams played a prince and sailor. Pearl saves his life and falls in love with him. The costumes and set seems dated by now but it's still worth watching anyway.
