1. ^Filmfacts - Volume 15 1972- Page 210 Under Michele Lupo's direction (excellent post-synchronization by Gene Luotto), the Italian production unravels a series of murders on a British estate. The Met Opera soprano, Anna Moffo, heads a cast of delightful players . . . The end result is a mishmash of film genres which are hilariously incongruous. This is not one of those terrible films that can be explained away as camp; it had to be deliberately planned the way it is (or else miracles still happen). The effective score by Francesco De Masi utilizes the comic results the opening bars of Tchaikovsky's First Piano Concerto punctuated with rifle shots. Vincenzo Tomassi edited to a solid 98 minutes. Film is being paired with "The Black Belly Of The Tarantula." ..."
