I'm only somewhat familiar with the Ultra series as a whole, but this is something that I've never heard of at all:

I know that the original Ultraman series aired in 1966 and then Ultra Seven followed in 1967... so what the hell is this? I thought maybe this was some kind of Chaiyo ripoff, but according to that page TPC were indeed the producers of the film. It also looks like it starred Akihiko Hirata.
So, can anybody just fill me in on this? Why exactly hasn't this film been caught up in the current legal dispute with Chaiyo like the other original Ultra series titles?
