His most well-known film outside Brazil is "Como Era Gostoso o Meu Francês" ("How Tasty Was My Little Frenchman", 1971). It was entered into the 21st Berlin International Film Festival. The film takes place in the sixteenth century and details the alleged cannibalistic practices of the (now extinct) indigenous Tupinamba warrior tribe against the French and Portuguese colonizers of the Brazilian littoral. The film is something of a black comedy about European colonialism—one that makes satirical use of the Brazilian modernist trope of "Antropofagia" ("cultural cannibalism"), then recently revived by the Tropicalismo movement of the 1960s—as well as a bitter commentary on the historical genocide of the indigenous tribes in Latin America and the gradual destruction of their civilization.
