At one point of the film, the character played by Max von Sydow tells some historical facts about the Medieval French composer Robert De Bauleac while listening to one of his work on a record player. When the film was released, a good number of music lovers tried to get a copy of the very same record in specialized stores which could never provide any for a very good reason: Robert De Bauleac has never existed and the composition heard in the film is none other than Antoine Duhamel's work. However the concerned peace of music, "Robert De Bauleac's Lament", has been since available as part of the complete movie soundtrack.
