The Fox and the Hound
Delayed half a year by the defection of the Bluth group, "The Fox and the Hound" was released in 1981 after four years in production. The film was considered a financial success by the studio, and development continued on "The Black Cauldron", a long-gestating adaptation of the "Chronicles of Prydain" series of novels by Lloyd Alexander produced in Super Technirama 70.
