Japanese Army of Darkness Poster: Bruce Campbell (Soup)

I collect a lot of movie posters. Originals, the cool double sided posters you can only get in the theaters. So whenever I see an international poster that looks this sweet, I drool a little bit. Of course, some of the drooling in this case can be attributed to Bruce Campbell. *sigh* he’s one dreamy B-movie actor.
I’m not quite sure what the “moooooon” thing is, or why there are killer whales swimming in the background, but honestly, I really don’t care. I just want this thing.

The main yellow writing across the top says ‘kyaputen Suupamaaketo’, which is a Japanese phonetic spelling and pronunciation of what would be “Captain Supermarket’.
What are they on they on about?
I agree this is a mighty poster however.
