I haven’t seen Sexcula. But then, that’s kind of the point: Not many people in the world have seen Sexcula. Luckily, we have the Grand Illusion to deliver little-viewed wonders like this 1974 Canadian porno. A mad scientist—Dr. Fallatingstein!—is distraught that the monster he created turned out to be impotent. Countess Sexcula is called in to help Frank embonerfy, and a caged gorilla and a hunchback named Orgie get involved, too. Sure, Canuxploitation.com refers to Sexcula as “a bit of a mess,” but as far as dirty pre-Halloween kicks go, you’ll get your money’s worth.
