Propp came up with the theory that there are 7 types of characters that appear in films, not every character has a clear role within the film and some characters have a couple of the character types within their role

The eight types of characters..

1. The villain — struggles against the hero.
2. The donor — prepares the hero or gives the hero some magical object.
3. The (magical) helper — helps the hero in the quest.
4. The princess or prize — the hero deserves her throughout the story but is unable to marry her because of an unfair evil, usually because of the villain. the hero's journey is often ended when he marries the princess, thereby beating the villain.
5. her father — gives the task to the hero, identifies the false hero, marries the hero, often sought for during the narrative. Propp noted that functionally, the princess and the father can not be clearly distinguished.
6. The dispatcher — character who makes the lack known and sends the hero off.
7. The hero or victim/seeker hero — reacts to the donor, weds the princess.
8. False hero — takes credit for the hero’s actions or tries to marry the princess.
