This document summarizes key elements of four different film genres: horror, comedy, action, and sci-fi/fantasy. For horror films, it notes that they are often set in isolated, gloomy places to enhance feelings of isolation and tension. Props like knives are commonly used instead of guns. Sound and lighting are important for building tension and fear. Comedies tend to be set in bright places and use natural lighting. They rely on over-the-top actions to elicit laughter. Action films feature unrealistic but exciting scenes in busy cities and use special effects for explosions. Sci-fi/fantasy films are set in imaginary places and feature futuristic props, with good versus evil narratives and advanced technologies emphasized through camera
