You're not necessarily showing your age. A lot of that stuff is out on DVD now.
I missed this thread before. I love the timeless classics, though I haven't seen as many as I should. Most of my favorites are already listed. Though I didn't see
Dune or
Highlander (sorry if they're there, I skimmed.) Those are a couple of great '80s sci-fi movies. You've gotta love movies like
Dune that were all done with miniatures and mock-ups because CGI was a long way off.
