Five Dolls for an August Moon (Italian: 5 bambole per la luna d'agosto) is a 1970 Italian giallo film directed by Mario Bava. It concerns a group of people who have gathered on a remote island for fun and relaxation. One of the guests is a chemist who has created a revolutionary new chemical process, and several of the attending industrialists are eager to buy it from him. Business problems become a moot point, however, when someone begins killing off the attendees one-by-one. It is an uncredited adaptation of Agatha Christie 's And Then There Were None .
