The document discusses how three main characters in a film are designed to represent different social groups and be relatable to the target audience. Sabrina, the villain protagonist, has atypical hair for a thriller character to make her more mysterious. Ben, the hero, wears modern, normal clothing to appear like a regular guy. Hannah, the victim/antagonist, is fashionable like popular characters and contrasts with the hero. The characters are the same age as the target audience to make them easy to relate to.
