“Under the Flags, the Sun is thus not only a cinematic memorial to the victims of the Stroessner dictatorship, but also a plea to look the past in the eye—and recognize the mechanisms that make dictatorships possible. This may be more important today than anyone could have imagined just a few years ago.” —Film-rezensionen.de

“Pereira develops a kaleidoscopic vision of his country under Stroessner’s regime, a form of visually rich jigsaw, allowing the viewers to think and build their own judgment on what they are witnessing. The strength of [his] film lies not only in its way of deconstructing the image of this regime, relatively unknown in the western world compared to the dictatorships of Brazil, Chile or Argentina, but also in allowing us to meditate on the dynamic power that determines the relationships between the West, particularly the United States, and the Third World during the Cold War and, in some respects, practically up to the present days.” —FIPRESCI (International Federation of Film Critics)

“What with the current turmoil that Western politics finds itself in, Under the Flags, the Sun is an important film in its own right to underline the dangers of authoritarian strongmen.” —International Cinephile Society

“Under the Flags, the Sun is undoubtedly highly effective in relaying to the average viewer what exactly happened in Paraguay from the ‘50s onwards.” —Cineuropa
