Black Capes

Black Capes is a 1947 Portuguese musical film directed by Armando de Miranda and starring Amália Rodrigues, Alberto Ribeiro and Artur Agostinho. The film takes its name from the black capes worn by the students at the University of Coimbra. The film was an enormous success at the box office in both Portugal and Brazil, despite criticism in Coimbra that depictions of the city and its musical tradition were not accurately represented.
