I watched Wonderful Galaxy of Oz last night which was a Digiview release that I got from Walmart for $1. The NJ Walmarts seem pretty plentiful in dollar DVDs if you know where to look (I often have to ask several times as many of the Walmarts here are rennovating and many employees don't seem to know where the DVDs are).
Last night, I needed something mindless to watch that I could have a laugh at and Wonderful Galaxy of Oz was good for that. I actually liked the voices, backgrounds and sound effects. The space plot was an interesting take on the Oz story -- the "tin man" in this story had a decidedly C3PO feel to him. I thought that making the scarecrow into "plant man" was kind of weird (but the character looks a lot weirder on the packaging then he does in the film). And although in the intro song and on the packaging they say Dorothy (who is blond and a blond Dorothy seems kind of foreign to me) had a mutant dog named "Talk Talk", Dorothy's dog is called Toto throughout the movie. Also, despite what the packaging says the film runs 75 minutes not 50.
When looking up this movie to find the ISBN so I can post it back on titletrader (which I still haven't found yet), I found some interesting things. First are some wikipedia articles which mention two space-themed Oz cartoons, a 26-episode series called Supêsu Oz no bôken (and I don't know if the film is part of the same series) and Space Oz No Daiboken which was released in the 90s.
Also, it looks like most of the Japanese animation released by Digiview comes from Enoki films, judging from the list of animated features including Galaxy of Oz, Thumbelina (which I can tell is the same from the previews), Puss in Boots (which I know was written up earlier as a Toei film so I don't know if the Enoki version is the same as the Toei one that got released by digiview although the artwork is definitely different than the artwork on the Digiview box) and the Adventures of Huck Finn. Some of the titles given to the films by Digiview are not the same as the original Enoki titles.
I have yet to view Puss in Boots or Huck Finn even though I own both, but I want to get a copy of Thumbelina since it looks like the best animated out of any of these. Also it looks like the Huck Finn, Thumbelina and Puss in Boots movies are all part of their own series which each ran 26 half hour episodes.
