I've still yet to see the original Flesh Gordon.
I even have a rather sad story about wanting to go see it. I was all into Star Trek and skiffy by then. That was 1974, and I was 8. So, they had an ad on TV. I distinctly remember that it was during the evening news or just after in the game show block, so sometime between 6:30-7:30 PM, on one of the three network stations. And they showed Flesh sword-fighting with a stop-motion creature. So, I saw that and was all excited, and wanted to go see it, and..... I found out what it meant to be rated X. Or, well, I learned that it was bad and naughty, and that I wasn't allowed to see it. But can you imagine?!? They ran ads for an X-rated movie on TV back in the day at hours like that. Man, we've really declined since then!
