Le roman de renard (or The Tale of the Fox) By LADISLAS STAREVITCH — 1930
(from Wikipedia:)
In the kingdom of animals, the fox Renard is used to tricking and fooling everyone. Consequently, the King (a lion), receives more and more complaints. Finally, he orders Renard to be arrested and brought before the throne.
This is the legendary feature film by Wladyslaw Starewicz (or Ladislas Starevitch, or Ladislas Starewicz, or Ladislaw Starewicz, or Ladislas Starewitch, or Ladislaw Starewitsch). It is also his only one, and he directed it with his wife, Irène Starewicz. The story is an adaptation of a compilation or medieval French legends called "Le roman de renart". It's an entertaining story, a social satire, but most of all a landmark in early animation. I find the stop-motion truly remarkable, even by Starewicz's standards. The facial expressions and the movements are very smooth and fluid.
It had a good reception when it was first released, but as it was wartime people quickly forgot about it. They later exploited in under the form of shorts, since it contains many independent stories with one linking narrative.
