Originally titled Zombie Bloodbath, this pile of scat from Del Tenney (The Horror of Party Beach) was filmed in 1965. However, it sat on the shelf for six years, until one Jerry Gross tacked it on to the bottom end of a double bill with I Drink Your Blood. Hence, the title change to I Eat Your Skin. (No one's skin actually gets eaten, which makes me wonder about the other movie.)
If you like your horror films with no scares and a strongly misogynistic bent, this one's for you!
