You are right. Its been many years since I’ve seen those. We have a bunch of them on tape so might have to refresh my memory!
Yup, it was Pia Zadora (back in obscurity again these days). I have "Santa Claus Conquers the Martians" on VHS. I watch it every other year. (It's just too awful to watch every year.)
