||Looney Tunes director Chuck Jones lets his imagination fly with this full-length mixture of live action and animation based on the classic story by Norton Juster. Milo, a bored child (Butch Patrick) in San Francisco, takes a mysterious journey through the titular phone booth and arrives in an animated fantasy land run by feuding numbers and letters. He meets all sorts of peculiar characters and joins forces with a "watch" dog named Tock and a lovable old coot called Humbug. Together they must restore order to the Land of Wisdom by rescuing the Princesses Rhyme and Reason, who are being held captive in a midair castle. Along the way, they run into the Doldroms, Alphabet City, a strange giant/short/thin/fat man, and even a "point of view." It's a land of bizarre puns and symbols, and it's up to the child to concentrate, learn the lessons, and save the day. Mel Blanc, Dudley Moore, and Paul Henreid lend their vocal talents to this unique and successful blend of live action, animation, and songs.
