Just in case you don't remember, or you've never even heard of this before, back in 1966 Toho and Greenway Productions bought two film treatments for a prospective movie called Battoman tai Gojiro or Batman Against Godzilla.

Unfortunately, the movie never happened, but it certainly would have been a sight to see. I love the fact that the production company at least considered making this movie enough to buy the treatments for it!

This project has been dragged back into the spotlight thanks to a Twitter user named Sean who posted some screenshots from the Wikipedia entry. He also shared a synopsis of the ending of the film.
