The third in Hammer Studios tits n’ blood vampire trilogy has plenty of both to keep fans happy (the other two being The Vampire Lovers and Lust for a Vampire). Peter Cushing is Gustav, a witch hunter who runs afoul of the evil Count Karnstein (Damien Thomas). Gustav has two sexy identical twin nieces (Playboy’s first twin centerfolds Madeleine and Mary Collinson), one a sweet innocent, the other a slut. After the Count turns the slutty sister into a vampire, she is captured by Gustav, but before he can destroy her, the Count swaps her out for the nice twin. The romantic lead figures out the Count’s plan before it’s too late and drives a stake into his heart, but not before Gustav gets an axe in his back. Cushing is great as always and the Collinson twins are capable actresses as well as nice eye candy. There’s also a great decapitation scene that will have you cheering too. Overall, a top notch Hammer horror flick.
