This document discusses narrative theory and Vladimir Propp's analysis of characters and their functions in Russian fairytales from the 1920s. Propp proposed that characters could be classified into clearly defined roles like the hero, villain, donor, dispatcher, and others. Propp's model fits stories like Star Wars well but not more recent nonlinear narratives. The document also links roles like the hero, villain, donor, and dispatcher to a film noir film about a recently graduated police officer working to bring down a local gang leader.
