After the story's introduction in the 1940's the movie cuts to 1983 where the story develops from then on. However, many parts of the 1983 segment actually happened in 1980 such as Wilson Pinheiro's death.
Farmers/killers Darly and Darcy Alves names are misspelled as Darli and Darci.
During the scene of Wilson Pinheiro's execution, the characters are watching a well-known moment from the TV series Vale Tudo. This wouldn't be possible since this series would only be released in 1988 while Pinheiro was killed in 1980.
