I know, I know, this seems like a bit of stretch in this painfully modern age, but spacemen and dinosaurs were top-of-my-mind in the 1950's and 60's

There were only 3 channels on TV -- mostly black and white -- and there was no smart phones, Internet or social media. The Day the Earth Stood Still came out the year before I was born. Star Trek didn't appear on TV until 1966 (I was 14). Game changer 2001: A Space Odyssey was in the theaters a couple of years later.
