This film earned the Oscar it got. Some very excellent traditional stop motion animation, combined with modern editing techniques.
The story is placed in a more modern world and given some new twists. A modern but deteriorating Russia set against an almost primal wilderness. The main character, Peter, has lost his Disney-like cuteness. And that's a good thing! He's a more streetwise but daydreaming Peter. Tough but lonely. The animation on the characters is simply superb. They even animated the fur of the wolf and cat!
Go see this animation as well as Dog, another one of Suzie Templeton's great little shorts.
