It was the second Portuguese sound feature film (the first was A Severa; a 1931 documentary by Manoel de Oliveira, Douro, Faina Fluvial was originally filmed without soundtrack, which was added afterwards). In fact, A Canção de Lisboa was the first sound feature fully produced in Portugal, in the labs of Lisboa Filme and with Tobis equipment.
Among the team were some of the greatest names of Portuguese culture of the day, such as painter Carlos Botelho (credited as assistant director) and the poet José Gomes Ferreira (editor assistant). Painter Almada Negreiros was the author of both promotional posters.
A Canção de Lisboa is still one of the best loved films in Portugal, with several of its lines and songs still quoted. —Wikipedia, the free encyclopedia
