"La Maschera del Demonio" aka "Black Sunday" is an excellent Gothic chiller with plenty of uncanny atmosphere,a good script and an okay cast.Princess Asa Vajda(lovely Barbara Steele)is executed as a witch.200 years later,she is revived and plots to take over the body of Katia(also Barbara Steele)."Black Sunday" is a perfect combination of Expressionist lighting and set designs and graphic bursts of gore and sensuality.The film is full of striking visuals and is truly one of the most beautiful black and white films I have ever seen.A must-see for fans of Italian horror.10 out of 10.
