finally saw it again!
I was dying to see this when it first came out--I was about 6 or 7, and the trailer looked SO exciting. I spent the entire movie going, "Dad, what's happening? Why are they shrinking those people?"
I searched for this movie for years afterward, and I finally lucked out and caught it on TCM a few months ago, uncut and in letterbox. I said almost the same things second time around, except now I was able to appreciate the fine Italian women in bikinis. Probably what my dad was trying to do while I pestered him with questions forty years ago. ;-)
