Anything ray Harryhausen did in the 1950s was Great!
Others were also great!
Giant Scorpions, Gila Monsters! Tarantulas! Mars Monsters.
Some not so great (The Giant Claw).
Drive in theater movies, but who went to watch the movie!
Sixty years later I still get a thrill watching them, not these silly superhero CGI movies.
Still waiting to see a movie called GOG which I missed back in the 1950s.
It just needed a prettier monster:
Amen.
Has anyone mentioned Twenty Million Miles to Earth?
I saw GOG on TV as a kid in the late 50s, and it spooked me for years, thinking that the overhead light in my room was going to turn into a Death Ray, and I could almost hear GOG and MAGOG coming down the hall to my bedroom in the middle of the night.
Pretty scary stuff back then, but these days we have Hillary causing even worse nightmares...
