In 1938 the great Abel Gance filmed the opera Louise of Gustave Charpentier. The leading part was played and sung by Grace Moore, perhaps the most famous Louise ever, who also made a great career in Hollywood as a film star.

Grace Moore sings Depuis le jour:

The charismatic French tenor Georges Thill (Julien) also played in several films and, besides having a singing career on stage, also made a name for himself as a great film actor.

Georges Thill and Grace Moore:

There are many cuts, but since the film was supervised by the composer, we can assume that he agreed with them. Unfortunately, the film is not subtitled, but the booklet contains an extensive synopsis with a detailed description of all the scenes.
