Francesco Dal Bosco was one of the most important contemporary Trentino filmmaker. A great experimenter of languages, he began his activity in avant-garde theatre and, at the beginning of the 1980s, he moved to the cinema. La notte che vola e Commesso viaggiatore are his most famous works together with La camera da letto, a 9-hour film in which Attilio Bertolucci reads his homonymous poem in its entirety.
