"The Black Cauldron" is an animated fantasy film produced by Walt Disney Productions and released in 1985. It is based on the first two books of Lloyd Alexander's series, "The Chronicles of Prydain." The story follows a young pig-keeper named Taran who embarks on a quest to prevent an evil warlord, The Horned King, from using a magical cauldron that can create an army of the undead. The film features a mix of adventure and dark themes, which was a departure from typical Disney fare at the time. Despite its innovative animation and unique storyline, "The Black Cauldron" received mixed reviews and was not a commercial success, but it has since gained a cult following.
