Limite is a film by Mario Peixoto, who was twenty-two years old when he made it in 1931. Influenced by Soviet cinema at the time, Peixoto was looking for an aesthetic of pure cinema and created one of the great masterpieces of poetic cinema, perhaps not so well-known like its European equivalents because it was made in South America. Here's a link to a close reading of the film with lots of pictures which gives a good idea about its content. Brazilian film director Walter Salles (Motorcycle Diaries) gave a masterclass about Limite at the last Cannes festival to celebrate the film's print restoration so hopefully it will be getting a DVD release in the near future.
And here are some fragments of Limite found on YouTube:
