The Voyage of Tanai

I saw this movie in the mid 80's and it has to be one of the best filmed movies ever. The cinematography was like nothing I've ever seen and with there being no dialog the visual aspect ends up telling the story. I realize it doesn't sound compelling but trust me it is. Should you ever see the movie you'll know what I mean. The boy playing the part of the main character was perfect. He doesn't seem to be acting and the other characters don't either. It's like you're watching a documentary with no commentary. They are showing the Polynesian culture in the most mundane ways (to them) but you are pulled in and you understand the story being told. I would truly love to own this film but it doesn't seem to be available in any format in the U.S.
