The Dinosaur and the Missing Link

The Dinosaur and the Missing Link: A Prehistoric Tragedy was created by Willis O'Brien in 1915, released by Edison Studios in 1917. The stop-motion animated tale concerns a courtship among prehistoric cave people, an ape-creature (the missing link), and a dinosaur. The real comedy comes in the intertitles, which would be quite at home in an Edwardian romantic comedy. I found this in an interesting article about the evolution of dinosaurs in movies at Vulture.
