Hey!
Watched this with my roommate the other night. It's a great movie. It always makes me cry a little everytime I see it. The dragon inspired my tattoo I got when I was 30. It came out in 1979. I watched it when I was younger and I've seen it twice since then. It's pretty cool if you like early anime. You can get it on Netflix (DVD).

The movie is available in English. Having a hard time finding the trailer in English though.
