Vladimir suggested that characters take on the role of narrative "spheres of actions"
Our group decided to compare this theory to Harry Potter to see which characters corresponds to which role.
These characters are:
1. The Hero, usually male, restores equilibrium by embarking on a quest. In our case, Harry Potter is the Hero which is clearly told through his name being the title, and him featuring in the majority of the film.
2. There is a Villain which creates disruptions, ruining the equilibrium. This is what the hero has to fix. In Harry Potter the villain throughout the whole series is Voldemort, but in each separate film there is also another minor villain.
3. There is a Donor who prepares the Hero by giving him/her an object or magical powers. In Spiderman the donor would be the spider that bit Peter Parker to give him the powers.
4. There is a Dispatcher notifies the Hero of the disturbance I equilibrium and sends him on his way. In Harry Potter, Hagrid would be the dispatcher.
5. There is a Helper who aids the hero on his/her quest. In Shrek, Donkey would be the helper.
6. There is a Princess or Prize which the Hero deservers throughout the story but cannot have due to evil, usually from the villain. The hero then obtains this at the end of his journey through defeating the villain. In Shrek the Princess would be Fiona.
7. There is a False Hero who takes credit for the hero's actions or tries to marry the Princess. In Frozen, Prince Hans would be the anti-hero.
