I remember in third grade seeing the movie section in the paper showing an ad called Night of the Blood Farmers with that curious R rating.
This must have been it.
You're correct and also titled Torture Island Barn Dance in the south.
Nothing exists more beautifully than nothing.
You might have been thinking of "Night of Blood Beast"...? Both "Blood Beast" and "Blood Farmers" were known for midnight drive-in favors back then. Often double featured. Under the distributor's given rights, a film cannot be multi-titled in the same country. However, it is very possible that this film is titled "Blood Farmers" in the US, but it would be titled "Blood Beast" in UK. Each distributor often retitle a film in each country for its marketing reason.
