The opening credit roll was animated by Hayao Miyazaki, except for two scenes by experienced animator Yasuji Mori. Assigned to animate a ring dance of Heidi and Peter, Mori wanted to analyze a movement of two real people, so Miyazaki and animation director Yôichi Kotabe did a ring dance in a parking lot next to their studio, and Mori shot them with an 8mm camera for reference.
