Disney movie archetypes
Movie: Tangled

Maiden: Rapunzel
Hero: Flyn Rider
Villain: Rapunzel's Mom
Trickster: Pascal
Wise Old Man: the vikings in the pub
Earth mother: The queen

These archetypes are used because they make something for a person to relate to.  People like having some sense of understanding and the usage of archetypes does that for us.  I also think that we inadvertently put these in all our stories because its a part of all of our lives.
