Bodanzky read Carrano's book in 1996 and, impressed by the theme, assigned Luiz Bolognesi to adapt it into a film and transpose its setting from the 1970s to the 1990s. In addition to keeping the film in the present, Bodanzky chose to make it a documentary-style film to create greater impact on the viewer. Bolognesi began writing in 1997 with the freedom to make changes to the original story. The film was shot in early 2000 in São Paulo, and was edited and finalized in Italy.
