There exist two versions of this film, the difference being the aspect ratio. In 1955 many cinemas didn't have the equipment to show CinemaScope films, so besides the original anamorphic version (aspect ratio 2,55:1) Disney filmed a spherical version (aspect ratio 1,37:1) where some of the animation was redone to fit the frame.
On home video, three versions were released: the widescreen version (LD & DVD), the Academy ratio version (VHS & LD) and a Pan & Scan version based on the widescreen version (DVD).
In 1975 the German version of this film was completely redubbed for unknown reasons. What is known is the fact that the 1955 dubbing was available in four channel magnetic stereo sound, the new version however was recorded in monaural sound.
The Greek version was entirely re-dubbed in the 2006 re-release.
