A Space Godzilla would have been the most amazing film ever made.
What is this? Concept art? Looks interesting.
These are by Katsuhiro Otomo (writer/illustrator of Akira), published in a 1979 issue of Japan’s version of Starlog. In it (to quote Toho Kingdom user Tamura) “Godzilla’s corpse washes ashore, followed by 2001-style head trips with Godzilla’s soul traversing the cosmos, his encounters with an alien entity, a final battle with a monster called Gamora, and Godzilla’s final evolution into infinity.”
It was, at the very least, proposed as a movie (using stop-motion for the kaiju), but I don’t know much beyond that.
