Interesting article about this film: 

"Although THE VAMPIRE AND THE BALLERINA (originally L’amanti del Vampiro ["The Vampire's Lover]) is certainly not the most important continental European or even Italian horror film made in 1960, it is nevertheless of significance for a number of reasons. In the first place, it marks the directorial debut of Renato Polselli. Polselli is one of the more intriguing and under-examined figures in European cinefantastique. A philosophy graduate whose films express a distinctive, personal take on psychology, sexuality and morality, striving for freedom from convention and hypocrisy, he continually explored and pushed the boundaries of acceptability." ~Cinefantastique
