It was released on June 22, 1955 and is based on the 1945 Cosmopolitan magazine story “Happy Dan, the Cynical Dog” by Ward Greene. Directed by Clyde Geronimi, Wilfred Jackson, and Hamilton Luske, the film was notable for being the first Disney animated feature produced in the CinemaScope widescreen format and was also the first Disney animated feature to be based on an original story rather than a traditional fairy tale or literary work.
