 The result is a sense of dynamic exploration of the spaces contrasting with the monumental appearance of the sets.Another innovation that L'Herbier employed for the first screening of the film was the use of recorded sound effects.For the scenes of Hamelin's take-off at the airfield, which is intercut with scenes of frantic activity at the Bourse, authentic recordings were made in both settings and then a composite blend of them was played back from records in the cinema.
