actually owned the 200' 8mm comp of this movie for several years before it ever aired on Channel 2. it wasn't shown too much, but after watching all 11 minutes of it as many times as I had, it was like seeing old friends with sound! it seems like I remember thinking "yeah, that's how they sounded in my head as well."
I like the movie, but it's not a great film. and the original Japanese version isn't much better either. it's longer, but definitely more boring than the US version. we all wanted to see Varan fly though, and that is kind of a fun little scene.
it would be kind of cool to see this movie on a legit release, but apparently it's one of the few "lost" Toho movies of the 60s. there were a few VHS releases back in the late 90s, but I doubt they had any real legitimacy.
