Mondo films are a subgenre of exploitation films and documentary films. Many mondo films are made in a way to resemble a pseudo-documentary and usually depicting sensational topics, scenes, or situations. Common traits of mondo films include portrayals of foreign cultures (which have drawn accusations of ethnocentrism or racism), an emphasis on taboo subjects such as death and sex, and staged sequences presented as genuine documentary footage. Over time, the films have placed increasing emphasis on footage of the dead and dying (both real and fake). The genre is also noted for the graphic footage of death and deceased people often shown in many such films, leading to the popular nickname of "death film".
