Not every Olympian reaches the fame and glory of a Michael Phelps, but in the new documentary A Fighting Chance, its the little-known athletes that are getting the spotlight.

While filming, director Morgan Neville traveled to South Africa, Vanuatu and the Dominican Republic to hear stories from three athletes training for the upcoming summer Olympic games in Rio, Brazil.

So many developing nations start at such a huge disadvantage ... they dont have any resources, he told HuffPost Rise. In the Dominican [Republic], for instance, at the boxing training facility there, where their punching bags are being held together by duct tape, you realize that these are people that just have incredible spirit.

While filming footage of the athletes arduous journeys, Neville said he realized that those in the West take a lot of our Olympic support for granted. Oftentimes, Olympians from developing countries are working with much less, but have hopes just as high.

The stakes are so much higher for these other athletes. For them, its really about what kind of a future theyre going to have. Hows their family going to do? Even: How are they going to survive? he said. So, in a way, they are doing their sports as a chance out of, in many cases, extreme poverty ... For them, its really a chance to have a better future. Its not just glory.
