I never expected I would one day discuss the English dub of an anime on this wiki, but here we go...
The Adventures of Sindbad The Sailor (シンドバッドの冒険) - 1962 anime film by Toei.
I saw this movie as a very young child, and many parts impressed me (especially the end with the gems, the giant stone bird and the waterfall). I remember watching it in English, but even then, I could barely understand the language.
The English dub of the movie has become rare, and I cannot find a version of this movie in a language I can understand.
Amazon used to have a VHS, and I thought it was a bit expensive and thought I'd worry about buying it later... now it's gone.
There is a Laser Disc for sale on Ebay. It's not too expensive... But it's a freaking Laser Disc! A format that is extremely outdated and very hard to watch on!
There is a freaking Betamax tape sold on Ebay as well. Betamax! You know, the VHS that wasn't a VHS... even older than Laser Disc. And it costs 40$. 80 if I ordered it!
The worst part is, there are SO MANY adaptations of the Sinbad the Sailor story around, especially in animated form, that it is very difficult to find the version I am looking for.
