The Phantom Tollbooth is a 1970 American live-action/animated fantasy film based on Norton Juster's 1961 children's book of the same name. Produced by Chuck Jones at MGM Animation/Visual Arts, the film stars Butch Patrick as Milo, alongside the voice talents of Mel Blanc, Daws Butler, Candy Candido, Hans Conried, June Foray, Patti Gilbert, Shepard Menken, Cliff Norton, Larry Thor, and Les Tremayne. Jones also co-directed the film with Abe Levitow, while Dave Monahan directed the live-action segments. Completed in 1968, the film was held up from release by MGM until late 1970 due to internal studio problems. The animation studio closed soon after the film's release, with MGM having no further involvement in the animation business until 1993 with the startup of their new Metro-Goldwyn-Mayer Animation studio.
