Lead actress Paula Souza stated that the role of Senhorinha was the most challenging in her 20 year-long career. She had to learn dialogue in a German dialect she doesn't speak while interacting with a baby in scene, keeping in mind she was playing a period character.
The main bulk of production was shot in six days, and it was mostly done at hard to reach locations. Producer Eduardo Christofoli commented by saying "it is impossible to shoot a Ulisses Da Motta film without having a dirt road".
Some actors have lines in what has become known as Riograndenser Hunsrückisch, a dialect that was commonly spoken by German immigrants who settled the south of Brazil and that is still spoken in the region to this day. The dialogue was translated by Heidi Collischonn, mother of actress Ursula Collischonn. She also taught actors Paula Souza and Frederico Vittola on their pronunciation. Director Ulisses Da Motta also learned some of the dialect to better direct the cast.
The script is based on director Ulisses Da Motta's paternal family history with some artistic license. He named the main character Senhorinha after his grandmother.
The cave where the scenes with the indigenous descendant character played by Marcos Guarani were shot was in fact an original dwelling-place of Brazilian natives in the past.
