José Wilker personally met Tenório Cavalcanti and his family and the movie was shot inside of the politician's house. According to Wilker, he got the blessing from Tenório's daughter in playing their father on screen since they thought Wilker was similar to Tenório and they'd only allow a movie version with Wilker in the leading role. The real Tenório Cavalcanti passed a year the following year of the film's release.
