How do we approach a figure like Mario Bava, a once obscure figure promoted to cult status? This book takes a new look at Italy's 'maestro of horror' but also uses his films to address a broader set of concerns. What issues do his films raise for film authorship, given that several of them were released in different versions and his contributions to others were not always credited? How might he be understood in relation to genre, one of which he is sometimes credited with having pioneered? This volume addresses these questions through a thorough analysis of Bava's shifting reputation as a stylist and genre pioneer and also discusses the formal and narrative properties of a filmography marked by an emphasis on spectacle and atmosphere over narrative coherence and the ways in which his lauded cinematic style intersects with different production contexts. Featuring new analysis of cult classics like Kill, Baby ... Kill (1966) and Five Dolls for an August Moon (1970), Mario Bava: The Artisan as Italian Horror Auteur sheds light on a body of films that were designed to be ephemeral but continue to fascinate us today.
