Overall, 'Secret Agent' serves as a poignant exploration of personal and collective histories, emphasizing how the past continually influences the present. It prompts viewers to consider the implications of living under a dictatorship and the role of cinema in addressing historical injustices. The film is not just a reflection on Brazil’s past but also a commentary on broader themes of political struggle that resonate universally, offering insights into the complexities of identity, power, and resistance.
