Italian giallo films have a peculiar allure. Taking their name from the Italian for "yellow"- reflecting the covers of pulp crime novels-these genre movies were principally produced between 1960 and the late 1970s. These cinematic hybrids of crime, horror, and detection are characterized by elaborate set-piece murders, lurid aesthetics, and experimental soundtracks. Using critical frameworks drawn from genre theory, reception studies, and cultural studies, Giallo! traces this historically marginalized genre's journey from Italian cinemas to the global cult-film canon. Through close textual analysis of films including The Girl Who Knew Too Much (1963), Blood and Black Lace (1964), The Bird with the Crystal Plumage (1970), The Black Belly of the Tarantula (1971), and The Case of the Bloody Iris (1972), Alexia Kannas considers the rendering of urban space in the giallo and how it expresses a complex and unsettling critique of late modernity.
