Katharine Ross?
i'm wondering if it's an IMDB misprint that THE katharine ross from The Graduate & Butch Cassidy was in this low-budget horror film, at the height of her fame?
shareNO. I remember when this was re-released in the early 80s (in my town, it premiered only played at the drive in with "Motel Hell"--no walk ins booked it apparently) and in all of the ads it boasted that it starred "Katherine Ross". There was NEVER any shots of her in the TV spots though. It may have featured (NOT starred) a Katherine Ross as some old lady character--but it was NOT THE Katherine Ross you and everyone else is thinking of. What a clever way to take a happenstance bit of casting luck (hiring someone with a famous name) and exploiting it! Ha!
But, ooooo what a struggle it was to wade through this flick. We only managed to do so to see "Motel Hell" afterwards. But for years after, my friends and I joked about "Pigs"! Ha! It was just lame-ass insane 70s crap repackaged with a wonderfully exploitive title and a big name! Brilliant!
