Did it receive any international distribution?

If Classic Doctor Who is any indication, copies of lost media can be recovered if someone is willing to look for it.

As far as I know, no, although there is more information about it in Spanish than in other languages ​​(with the exception of Japanese, of course).

It would been nice if they added the dubs for the other movies, but I guess SF didn't want to spend too much on a niche item. I'm still glad that this is even a thing. If you told me back in the early 2010s that SF would release Kamen Rider and other Toku on Blu-ray, I would not believe you.
