This movie, The Gods Must Be Crazy, is a 1980 comedy that also touches really well on the state of encounter between the "overdeveloped" world and the "underdeveloped" world. Although the condition of the bushpeople presented is an extreme reality, the whole movie is great for understanding some of the dynamic of cultural interaction and perspectives.
I recommend the first 16 minutes, if you have the time. They are especially poignant, and really put into perspective - through the contrasting of the extremes - the actual differences that exist between between "overdeveloped" society and "underdeveloped". I think that the contrast that they lay out is one that may be easily overlooked by us, and I think the movie does an excellent job - in humor as well - laying out that context in a way that we may intuit, but have difficulty clarifying ourselves.
Although it uses extremes, this beginning also portrays very well the actual *dynamic* that really does occur when the material development of the "overdeveloped" reaches the "underdeveloped" over and above (or, in this case, completely outside of) the context of mutually respecting relationships. You will see how the introduction of one coke bottle can almost destroy a community living a simpler, more primitive life - and, more importantly, why it does so.
Although Latin America is not at the level of primitiveness of the African bush, there are certainly tribes in certain areas that are - or were until recently - similar, and have been affected likewise by the arrival of outsiders. But even outside of those several direct similarities, the general *dynamic* expressed in the movie can be seen throughout all of my experiences in Latin America and Ecuador. It can hopefully cause some reflection on the *source* of what is popularly called "third-world" characteristics in Latin America, and the resulting flight in immigration to the US.
But the movie is funny, I found it entertaining and relate-able (several of the main characters are missionaries and volunteers), and the message laid out in those first 16 minutes continues as an undercurrent throughout, until the very end. It would be a great movie to talk about.
