Nina (Heitor Dhalia, 2004): in my opinion his best movie, and one of the best movies that were done recently in Brazil.
O Cheiro do Ralo (Heitor Dhalia, 2007) was based upon a book by Lourenço Mutarelli, and the interpretation of Selton de Mello is very convincing; the movie doesn't follow the text literally, and this is clever since the book was written in the first person, by a narrator who is not trustworthy.
À Deriva (Heitor Dhalia, 2009): From the middle to the end, the direction of actors gets better.
Serra Pelada (Heitor Dhalia, 2013);
Árido Movie (directed by Lírio Ferreira, 2005, and also with Selton Mello; for me it has the same metaphorical, dreamlike atmosphere as Dhalia's movies, and passages that feel equally uncanny);
"Naquela Mesa" (composed by Sérgio Bittencourt, here singed by Nelson Gonçalves and in Árido Movie by Otto);
