During one of the interrogation sessions, the chief of police Sergio Paranhos Fleury - played by Cássio Gabus Mendes - talks about his dream of having a boat and live in Ilhabela. In 1979, 10 years after the facts depicted in that particular scene, Fleury would die in an unexplained drowning in Ilhabela after falling from his boat.

Daniel de Oliveira also played a real victim of the Brazilian military regime in Zuzu Angel.
