The Last Unicorn directed by Rankin and Bass

The Last Unicorn is an animated movie released in 1982 and directed by Arthur Rankin Jr. and Jules Bass. It follows the story of a female unicorn who sets off to find out why and how all the other unicorns have mysteriously disappeared.

On her journey, she meets enemies as well as friends. One friend, a bumbling wizard, accidentally turns her into a human in order to save her from an angry fiery bull. This saves her from the fiery bull who was only after unicorns, but creates a whole new set of problems. The Unicorn and her friends are able to find the man responsible for the disappearance of her relatives, but will they be able to defeat him and his magical bull? Watch the story, and find out. Parents would want to be aware that there is one scene in the first few moments after she is turned human where the viewer can guess that she doesn't have any clothes on. Nothing is visible or sexually suggestive. Her hair covers her up enough, and her friends quickly come to her aid to give her clothes.
