I know there's a couple of Schnaas films that are hard to find. A Goblet Of Gore is one.

that made me laugh out loud!

Brain Damage, street trash, class of nuke em high!, maniac cop, deadly spawn, the naked lunch, scanners

well terror toons is hard to find but it is not a gem,and doll graveyard is pretty rare.Also one movie that should never have been made was subhuman(too much talking lol),oh yeah final patient is good and rare!

A couple more
 

Suicide-apparently rare but its from Germany and quite a shocker
What about the Guinea pig films: Flowers of flesh and blood, He never dies, The Devils Experiment, Mermaid in the Manhole
God Of Vampires

I may have missed a guinea pig or two, hope this is what you are looking for

Killer list!!!!!!!!!!!!!!

some things are hidden for a reason
