Watch on 123Movies. O AMOR NATURAL is a documentary film about the erotic poetry of one of the greatest Latin American poets of the 20th century, the Brazilian Carlos Drummond de Andrade (1902-1987). The erotic poems of Carlos Drummond de Andrade, a household name in Brazil, remained unpublished during his lifetime, as he feared they would be deemed pornographic. In this celebration of his poetry and sensual vision, elderly residents of Rio read his poems and comment on their graphic, voluptuous imagery with tremendous candor and enthusiasm.
