If you've been around developing countries, you've probably seen foreign tourists visiting underprivileged areas. They often spend good money that boosts trade in those places, but quite a few people consider that kind of attention a dismissive activity that reduces locals to mere spectacle for wealthy globetrotters trying to look smart or socially aware. Is tourism beneficial for poverty-stricken areas? "Tem Gringo no Morro" (AKA "Gringo on Slum") answers that question with authentic on-location footage from Rocinha in Rio, Brazil, and excellent interviews with both locals and visitors, including tour guides and community leaders who actively promote and profit from foreigners' visits. Mixing human interest and socially engaged journalism, the movie offers an in-depth look at the industry and the concrete, often amusing experiences of locals and tourists. It is a clever and thorough account of an economic reality that remains largely underexposed, and an enjoyable, thought-provoking film to watch. As a film editor who's worked on documentaries myself, I know that is quite an achievement for a documentary that lasts less than half an hour. Whether you find this online, on TV or at some festival, give it a go.
