The world's geography is not realistic. Geography is not real. Borders are only closed to people but they are open to products. There is another type of geography outside of this matrix. Because of this we noticed we were talking about much more than just Latin America. That was very important to put the film on another level. Based on this idea, we knew that we were not in this world any longer.
They didn't need to be specifically South American or Latin American. Instead we discovered we were talking about human beings in general. We realized that these are not issues only pertinent to Latin America: poverty, misery, consumerism, etc.
We discovered this halfway through the process. When we started making the film there were some lines of dialogue in Portuguese, but we then changed our minds. The film started from very specific issues in the world, in particular Latin America, but halfway through the journey we felt the necessity to have more universal ideas that were not so specific.
