A pretty decent adventure film from 1985 offers us several small groups of characters, each going into the wilds of the Amazon seeking different kinds of treasure. The movie is downright imaginative in the unpredictable kinds of trouble they encounter seeking out gold, diamonds or oil.
The good thing about the movie is how it depends on characterization although the visuals are great too. It's much better than most of the clueless action movies of 2007. For one thing the camera holds steady instead of shaking all over creation trying to fake suspense. Most of the 2007 era cheap tricks --- such as the vim vim vim vim sound tracks weren't invented yet.
Expect a disparate bunch of characters, mostly bad, a couple of girls with legs, and more fearful jungle creatures than you ever guessed existed.
After the movie, buzz down to Manaus, Brazil and spend a few days seeing things first hand.
