1950’s was space fantasy movies, with a couple of exceptions. All of the radioactive bugs and monsters were kind of silly.
The end of the 50s and through the sixties is where things started getting good.
Kinda liked “Devil Girl From Mars”, a British flick that was more psychodrama than SF, though she came to Earth in a spaceship that looked like a serving dish with a rotating rim.
Liked where she stares down an earthling until he’s a gibbering idiot. Those eyes!
The actress is still with us. She’s 97.
