Remember when discovering a trailer for a Japanese monster movie in ENGLISH was a rare thing? Both this movie and The X From Outer Space never got theatrical releases here in the States, but both have English trailers. Obviously done for marketing, but there was no way of knowing that back in the day.
Now we can see most of these rare trailers on youtube. Takes a little of the fun out of it, doesn't it?
I don't even know if this dub matches up with the one that we hear now. It sure is an exciting trailer, isn't it? It would have worked on me had I been old enough to see the film in the theater
