The 1997 short documentary Recife de Dentro pra Fora (Recife from the Inside Out) was done by Kátia Mesel and won 26 awards. It was inspired by a poem (“O Cão sem Plumas”) by João Cabral de Melo Neto, and his life on the Capibaribe river. It’s a little hard to hear at first but then the images and song take over and it’s pretty cool.
The Recife-born poet wrote the lengthy poem upon being strongly impacted by the news that the life expectancy in Recife, at the time (in the late 1940s), was just 28 years. When he wrote it, he was residing in Barcelona and thus penned it from his own memories. You can read it in its entirety here (PT), as well as an interpretation of its meaning.
