I remember picking up this movie when i worked at a video store it was dubbed in english and distrubited by manga
I liked the movie and remember the story well i didnt know there was a tv series altho im not surprised but honestly id rather subs than dubs not for the voices but you miss some of the emotion the voice actor is trying to impress onto the audience and with the translation you always lose something
But being that it's so old i doubt it was ever dubbed if you haven't found it already still you should get it with the subs im sure it's well worth it
