Sleeping Beauty (1959)–style approach. Both directors brought Milt Kahl out of retirement to create new character designs for Taran, Eilonwy, Fflewddur Fflam, and the other principal characters. Hale and the story team (including two story artists David Jonas and Al Wilson that he added) heavily revised the film, by which they capsulized the stories of the first two books. They also made some considerable changes, which led to Sisson's departure as she developed creative differences with Hale and the directors. Animators John Musker and Ron Clements, also citing creative differences, were removed from the project and began development on The Great Mouse Detective (1986). Displeased with Gerry's concept for the Horned King, Hale turned the Horned King into a thin creature donning a hood and carrying a spectral presence with shadowed face and glowing red eyes. His role was then expanded into a composite villain of several characters from the books. Taran and Eilonwy eventually acquired elements of the past designs and costumes of earlier Disney characters, especially the latter, who was drawn to resemble Princess Aurora. Casting According to Musker, Gary Burghoff of M*A*S*H fame had auditioned as Gurgi. He tried numerous vocal iterations since Ted Berman had no idea how the character should sound like. After three hours, the directors grew frustrated and Burghoff, who had refused to leave, was thrown out of the studio. By 1982, John Byner, an impressionist, had been cast in the part. After Bryner was shown the character concepts for Gurgi, he felt inspired to add a "child's inflection" when creating the voice. In January 1981, Hayley Mills stated she was being considered for the voice of Eilonwy. That same year, Mills hosted an episode of NBC's Disney's Wonderful World, in which she met with Hale and the directors to discuss the part. The role eventually went to Susan Sheridan. According to Sheridan, she recorded the voice on three separate trips to the Disney studios. In a 1983 Disney Channel special titled Backstage at Disney, Hale stated that Jonathan Winters was voicing King Eidilleg. The role eventually went to Arthur Malet. Test-screening and editing Shortly before the film's initially planned 1984 theatrical release, a test screening for the rough cut of The Black Cauldron was held at the studio's private theater in Burbank, California. After the film, particularly the climactic "cauldron-born" sequence, proved to be too intense and disturbing for the majority of
