Cast
From "The Psychotronic Encyclopedia of Film":
Victor Jory leads a group of 200-year-old scientists who have managed to stay alive by putting women in a tub of chemicals and sapping their energy through wires attached to headbands. Without the stolen female energy they turn to stone.
From "Leonard Maltin's Movie and Video Guide":
BOMB. Jory and his followers stay immortal by siphoning off the life forces of others. If they don't get renewed, they petrify. So does the movie.
