Once Upon A Time

- Žánr: Animovaný
- Režie: Hideaki Kitano
This short animated film was shown at the Seiko Pavilion during the 1970 Osaka Expo. It tells the story of a day when time is thrown into chaos by an alien prank, and speaks to the importance of time. The rapid change of the seasons is full of the charm of metamorphosis (the process of changing shape), which Osamu Tezuka loved.
