This animated film was to be helmed by Pete Burness, who was a director on UPA's Mr. Magoo theatrical cartoons, produced for Columbia between 1948 and 1959. Burness resigned after disagreements with producer and UPA owner Stephen Bosustow. Jack Kinney, who directed many of Walt Disney's Donald Duck cartoons, became the final choice to helm the film.

Kathryn Grant was an obvious choice to voice the Princess. She had played the Princess in Columbia's highly success box office hit, "The 7th Voyage of Sinbad" (1958) the previous year.

The first full-length animated feature to be distributed by Columbia Pictures.

UPA's first full-length animated feature.

The first animated movie to be dubbed in Spain. All earlier animated movies were dubbed in Latin America.
