The Glass Slipper is a charming retelling of the Cinderella story, eminently suitable for both kids and adults. Leslie Caron plays Ella, the plain-Jane stepsister of beautiful but mean-spirited Birdena (Amanda Blake) and Serafina (Lisa Daniels). While stepmother Widow Sonder (Elsa Lanchester) arranges wealthy marriages for her natural daughters, poor Ella hasn't got a chance.
