Yea, its pretty rare, i am from Austria so i've done some research too and came across the same site, Buena Vista (Disney) bought the Distribution rights but than dropped the movie...
BUT, the thing is... The Director worked a Year in Japan, during that time he got a tiny Japan distribution Deal and thats why you wont find any dvd on the european market... it only got released in Japan (english audio, japan subs). There are probably only 500 copys in japan...
Look here! [
Some Japan ebay seller offered it couple of years ago, if only someone knows who this ebay seller was... or someone knows a diffrent ebay seller from Japan who sells this kind of movies!
Does someone know how i can come in contact with toddly6666 ?
There is still hope that i can get my hands on one copy and upload it, otherwise this will be lost and dead forever.. like you said, nobody knows about this movie
