The Last Unicorn is an animated film produced by Rankin Bass based on the Peter S. Beagle screenplay of the same name. The movie follows the unicorn, who learns of her kin's disappearance and journies outside of the safety of her home to defeat the red bull who keeps her sisters prisoner. On her journey she is joined by a magician and a mysterious woman who aid her in her quest. With their help, and a fair amount of drama along the way, the unicorn frees her people.
Mia Farrow is known for her role in the TV movie Peter Pan, not to be mistaken for the Disney animated feature, as Peter Pan. In The Last Unicorn, she serves as the titular unicorn the film is named after.
Alan Arkin is a Jewish-American actor with a prolific history spanning into the 21st century, with the TV show The Kominsky Method. He voices the magician Schmendrick in this film, using his magic powers to aid the unicorn.
Tammy Grimes is a twice-Tony award winner, known mainly for her roles in musicals. She plays no minor role in The Last Unicorn, as Molly Grue helps the Unicorn to find the land where the red bull has been hidden away.
Sir Christopher Lee plays King Haggard in the film, the main antagonist pushing against the freedom of unicorns. He also voiced the same character in the German version of the film. You may have heard of Sir Lee through a few of his smaller roles.
