In the 2001 film ‘Harry Potter and the Philosopher’s Stone’ directed by Chris Columbus: Propp’s theory of stock characters can be applied

Harry is the hero, because he is the protagonist carrying out the quest.

Voldemort is the villain because he is the main antagonist, and actively blocks and opposes Harry’s quest.

Dumbledore is both the donor because he provides Harry with the knowledge of his origins and magical abilities. He is also the dispatcher because he sends Harry on his quest.

The helpers are Ron and Hermione because they aid the hero, Harry, throughout the film.

The princess can be considered Ginny because she is the object of Harry’s affections.

Draco is the false hero because he disrupts Harry’s success by making false claims.
