Much of my childhood was spent watching monster movies. That was in the days when the TV stations aired everything, including anything in black and white. Within about ten years of that, all the black and white films and shows starting disappearing. Voyage to the Bottom of the Sea had one season in black and white and three in color, and suddenly it was hard to find the first season. And the movies that I watched every Saturday that came from the 1950s and 1960s started disappearing. Even the color movies have largely disappeared now.
There were many films about the fears of what atomic power would do or our push into scientific fields. Them! had giant ants roaming the sewer systems of Los Angeles (with James Arness of Gunsmoke). The Creature From the Black Lagoon had an underwater creature stalking people (Ricou Browning did the underwater stunts without diving gear). The Fly, which starred David Hedison (though he was then using his first name, Al), had a scientist experimenting with transporter technology and ending up part man, part fly.
A few really scared me. There was one involving rats in a basket being put over someone’s head (no clue what the title is). In another, shockingly for the time, a man’s arm got torn off on camera (I believe that was The Brain That Wouldn’t Die).
And then there was Godzilla, and all the monster movies that came with it like Rodan and Monster Island. I think I saw the original only once or twice. It had a very different tone, more suited for the fears of science gone wild, so the local channels may have passed on it in favor of the other movies. Those were just plain monster-destroys-Tokoyo, and Godzilla even became a good monster with children
In 1977, NASA named the first space shuttle after the starship Enterprise of Star Trek. Now Godzilla has a constellation named after him.
And if you’ve never seen this, Bambi Meets Godzilla. It’s an early fan produced film that I saw at a con in the 1970s.
