Here are some words from Krug himself...David Hess:
"Well, its a real thrill to know that after all these years there are still fans out there who appreciate 'Last House'. The film was never meant to be anything other than it was, a gruesome expose of what could happen in this crazy world we live in. Most of the people involved in the production were and are at heart pacifists. We tried to go over board in our telling of the story in order to stop the impending violence that at the time was spreading like a cloud throughout the world. Lofty ideals, but we were all still very young." ~David Hess
