This document discusses the key elements of different film genres including horror, comedy, action, and romance. For horror films, common characteristics are a "final girl" character, the use of weapons as props, and isolated or urban settings. Comedy films vary more but often feature silly and serious characters and costumes that represent the characters' personalities. Action films typically have settings in big cities and feature weapons as props, while costumes depend on the type of action (e.g. superheroes vs police). Romance films usually focus on just two main characters, have romantic locations, and feature simple costumes and soundtracks that match the mood of each scene.
