Binro the Heretic SHIT! I loved the Hell out of this movie as a kid. I used to rent it from the crummy mom & pop video store down the road from our house. I can still remember the cover with the screaming astronaut and the tagline "You can feel them in your blood!"
My friends and I used to get this, "Chopping Mall", "C.H.U.D." and "Night of the Creeps" whenever we were in the mood for a weekend gore film fest.
