Horror films use certain cinematic techniques and conventions to create suspense and fear in the audience. These include high and low camera angles to portray vulnerability or power, extreme close-ups to build tension, and isolated or deserted settings. Common horror film themes involve death, characters unable to escape threats, and icons representing the villain's methods. The characters typically include protagonists, psychopaths, curious teenagers, victims (with at least one survivor), ghosts seeking revenge, demons, and serial killers with signature killing styles.
