The 50 Greatest Cartoons of All Time, as selected by a panel of animators.
This is now considered to be a Betty Boop cartoon, but she has only a cameo role, and she was still a dog at that stage in her character evolution. The dog ears were later adapted to be hoop ear rings.
The Max Fleischer cartoons from the 1930's were made very differently from modern cartoons. Today the script for cartoons is written first, then recorded by the voice actors. The director makes a storyboard sequence, and the animation is often done in assembly line fashion, frequently in East Asia, where semi-skilled labour costs are cheap.
With Betty Boop cartoons, the animators were often given a song which was to be included, and they built a cartoon around it. With the Fleischer Popeye cartoons, the voices are never synched to the lip movements. This is because the cartoons were fully animated before any dialogue was recorded, and the voice actors ad libbed their lines while watching the silent cartoon.
