Vladimir Propp was a literary scholar who developed a theory of narrative structure and character types. He proposed that all stories contain eight character archetypes, including the villain, dispatcher, helper, princess/prize, father, donor, hero, and false hero. Propp's theory influenced filmmaking and suggested that these character types appear in consistent narrative patterns, such as the hero rescuing the princess from the villain. The document then provides examples of how Propp's character types appear in modern films like The Dark Knight, Avengers Assemble, and The Amazing Spiderman.
