Dublado e Legendado no OverFlix. German director Werner Schroeter invited his favourite opera singers to a 13th century abbey near Paris. There was no pre-planned action. There was no script, no continuity. On the other hand, there were precise constraints that provided the rules of the game: the setting, the Abbey of Royaumont, and the chosen participants. Each singer came accompanied by a person of his or her choice, and worked on an aria chosen by the director.
