Wasn't this a big Hollywood production? Couldn't they afford to film on location? The sets of "Bolivia" look like they were filmed on location in rural California with local Mexicans as extras. If anyone has ever been to Bolivia (or even opened an encyclopedia), they know that Bolivians look, speak, and dress nothing like Mexicans. Watching this "classic", I couldn't help but be floored by the incredibly poor job they did in the closing sets of the film. Any historic value the film might have had went down the toilet for me during those last scenes. If you are primarily interested in movies for their popcorn entertainment value, don't dispair, as you probably won't even notice this flaw. For me, it really ruined any value the film might have otherwise had. Its like casting Keanu Reeves as Hamlet, and somehow he pulls it off, but at the end "Bill" comes out then he an Hamlet embrace and say "Excellent!". Oh never mind.
