I fell into this movie, broadcast by Belgian 2, in the scene where the evangelists travel up the river. The cast immediately caught the attention: what are all these actors, who usually don't play adventure type characters, doing in the Amazon?! Then Berenger is shown in a kind of nudity I thought US/Hollywood culture forbade. This absence of hypocrisy combined with quality actors made me sit straight. I had already missed a lot, but there was plenty of great and convincing story telling left. People struggle, try over and over to keep on going when things go wrong. Cultures try to interact but fail in different ways. Several of the main characters die of unexpected but reasonable events. And everything is so well set, framed and timed that it keeps watchable. The scene where Bates, dressed as a native exorcist, dances on her grief over a horrible loss was beautiful. There's MAYBE one scene just a bit artificial, where Hannah has pulled up a leg to hide some of her nudity for The Camera: it contrasts with her subsequent confrontation with Moon where she doesn't show any embarrassment.
The supporting acting by natives (mostly people who had only just adapted 'civilization' and who could still remember village life) is surprisingly good. The native language that was created sounds really well, not like any language I've ever heard, and it is spoken consistently as far as I can hear. The final shot is impressive, and the accompanying music sublimely subtle. I really must see the first 30 minutes some time!
