Medicine Man

All of the elements are here for a movie I would probably enjoy very much, but somehow they never come together. "Medicine Man," which is shot on location in the rain forests of the Amazon, has the great, grizzled Sean Connery as its star, doing research countless miles up an anonymous river with Lorraine Bracco, a tough-talking scientist from the Bronx. If this had been some dumb adventure movie, it would probably have been terrific. Alas, it is a "relationship" movie, told along lines of timeworn weariness, and since that is not bad enough, it also throws in several Serious Issues for the characters to discuss.
Connery, first seen wearing an Indian headdress while thoroughly marinated in an intoxicating jungle potion, is an eccentric Scotsman who has been doing research by himself for so long that he has almost forgotten what pajamas look like. Bracco reminds him of them, and other things.

She's the head of the organization that is financing him, and responds to his call for a research assistant because she wants to find out what he's doing out there in the jungle.

It goes, I think, almost without saying that Connery will resent a "girl" turning up as his helper, that Bracco will be a liberated woman, that they will fight, that together they will overcome great odds, and that eventually they will find themselves in each other's arms. It also goes without saying that there will be a lot of snakes and ants in the jungle (and one mosquito - announced with a loud buzz on the soundtrack).
