There was a movie called “Anachronism”, I think. It was a short about a caveman running from a dinosaur until another caveman calls the dinosaur on the historical inaccuracy, which somehow makes the dinosaur poof out of existence. I can’t seem to find anything about it, though it would probably help if I could remember the director/creator that the films in this series were named for.
Has anyone else seen these or know anything about them? Thanks!
