I have very distinct memories of seeing both Wizards of the Lost Kingdom I and II on television when I was a kid which I didn’t recall until I watched the MST3K episodes, which was really weird.
I remember seeing The Creeping Terror on tv. It was quite frightening for someone 5 years old!
Only one. Mac and Me. In theatres. Weep for me.
But they were traveling, crime fighting, bachelors of leisure. None of those girls wanted to live in that van.
And Max never got further than a pretty chaste kiss anyway.
The ones I’m pretty sure of:
Revenge of the Mysterons from Mars
Gamera vs Barugon
Gamera vs Gyaos
Gamera vs Zigra
Gamera vs Guiron
The Corpse Vanishes
Godzilla vs Megalon
Godzilla vs Ebirah
The Killer Shrews
Bride of the Monster
This Island Earth
Gamera vs Jiger
H.G. Wells’ The Shape of Things to Come
There may well be a few others, especially crappy sci-fi and horror films. I’m a relative newcomer so I haven’t seen a lot of the old episodes yet.
