Giallo films are a genre of Italian cinema that emerged in the 1960s, characterized by their blend of horror, mystery, and thriller elements. The term "giallo" means "yellow" in Italian, referring to the yellow covers of crime novels that inspired these films. They often feature stylish visuals, intricate plots, and a focus on psychological tension, with a mix of violence and eroticism. These films typically involve a detective or amateur sleuth trying to solve a series of murders, often with a masked killer. Notable directors of Giallo films include Dario Argento and Lucio Fulci, who helped define the genre's distinctive style and themes.
