Film in which Ana Hatherly presented a remarkable synthesis between the pulse of the moment lived in Portugal after the 25th of April and an aesthetically avant-garde and refined vision, joining a series of fixed iconographic images, evocative of the revolutionary moment, with the collective sound of this moment . It is a powerful film that thrills, in addition to questioning and reflecting on the very status of the image (fixed and in motion) and language. Revolution is a film of unmistakable modernity and of a remarkable experimental and political character.
