Propp analyzed fairytales and identified common character types including the villain, dispatcher, donor, hero/heroine, and princess. Todorov proposed narratives follow a structure of equilibrium, disruption, recognition, attempts to repair, and restored equilibrium. Both theories are exemplified in the Harry Potter and Jurassic World films - Harry Potter includes the expected character types like Voldemort and Dumbledore, while Jurassic World progresses through the narrative stages from a smoothly running park to disruption by the Indominous Rex and restoration of order.
