Prehistoric Peeps(1905)

A scientist dreams of prehistoric monsters. He awakes in a cavern. A dinosaur chases him, even though he tries to shoot it with his revolver. The chase continues onto the surface. The professor meets a group of prehistoric women, who flee when other monsters appear. The professor's wife finds him sleeping in the laboratory, surrounded by fossils, and wakes him with water from a siphon. This short film is only viewable at the BFI, and its generally believed to be the first film depiction of dinosaurs, here accomplished through the use of simple pantomime costumes.
