One of maestro Bava's least known films may actually be his best: A scientist invites several of his friends and business associates to his villa somewhere on a remote island. Once there they try to buy an important formula from him; when they are killed off one by one, everyone suspects everyone else of being the killer. Superbly stylish sets, photography and direction in Bava's quint-essential interpretation of Agatha Christie's Ten Little Indians; he turns it into a corny slasher movie. Bava also edited the picture. Wonderful 70s soundtrack by Piero Umiliani. Cinematography by Antonio Rinaldi, who did more films with Bava. English title: FIVE DOLLS FOR AN AUGUST MOON. Bava followed this with the more violent, similarly plotted ANTEFATTO.
