Three Early Cartoonist Filmmakers
"The Flintstones" are a more recent example of a cartoon based on prehistoric times, but as you can see, the theme started years ago.
Tony Sarg was an illustrator and a puppeteer who created a kind of animation that is not done with drawings, but with a frame-by-frame filming of a silhouette marionette (a puppet with jointed limbs that are moved with strings). In this film, called "The First Circus," Sarg and co-animator Herbert M. Dawley imagined what a prehistoric circus might be like.
