Hi, I am just adding to the topic with
Last Days of Planet Earth (1974) [LV12862], which I just picked up.
A Japanese movie, this is the Pan and Scan dubbed American version of Prophecies of Nostradamus 1974. This movie never saw any Japanese release on home video due to its portrayal of irradiated humans (this is and continues to be a very sensitive topic in Japan for obvious reasons). It is currently under self-imposed studio ban by Toho, which is a shame because it is a truly unique, terrifying movie. The American version has the banned scene, where two mutated people fight over a dry dirt landscape over a single worm. I have transferred the disc with a Domesday Duplicator and am archiving it.
