Jorden Er Flad or The Earth is Flat is based on the play Erasmus Montanus, from the classical era in Danish literature, by Ludvig Holberg. Director Henrik Stangerup had the play translated into Portuguese, and adapted it for filming in contemporary Brazil. In this comic movie, a group of villagers have scrimped and saved to send their fellow villager Erasmus Montanus (Fausto Wolff) away for an education. When the boy returns to his village, he is stuffed full of book-learning of a kind which is of absolutely no use to those of the village. The boy, rather than seeing his situation clearly, continues to spout learned platitudes, including the incredible observation, "the earth is round," supported by nothing other than his authority as an "educated man." Understandably, his posturing provokes derision.

Singer Laura Monteiro (Montiel) is murdered by her old protector João Fernandes de Oliveira (Giachetti), who has found out her love affair with Assis (Carlos Alberto). Favela-girl Belén (also Montiel) is the look-alike who takes her place, unaware she is being used by a gang that smuggles precious stones sewn in Carnival costumes. Written by fabreu
