Director Thor Stephan's delightfully fluffy concoction "Sex Invaders" is a sci-fi knock-off full of kooky humor. It's warped in warped speed, in fact. With a cast headed by the ever-delicious fantasy Vince Rockland, this costume epic is one hell of a good porn show at the same time (when the men look as dreamy in shiny vinyl pants as they do out of them, you know you have something unique).
