Trivia

The original script revealed Claudin to be Christine's father, who abandoned her and her mother in order to pursue a musical career. When this was excised from the final film, it left Claudin's obsession with Christine unexplained.

The bronze sculpture of Christine Dubois (Susanna Foster) was made by co-star Nelson Eddy, who was an accomplished sculptor.

On 21 May 1943, the finished film was rejected by the Hays Office because of a "number of unacceptable breast shots of Christine" in her dressing room. It has not been determined if the offending scenes were deleted or re-shot, but the film was released in Aug 1943 with Production Code Administration approval.

In the scene where the three heroes escape the Phantom's crumbling lair (which involve the three characters running from a cave-in) only Susanna Foster appeared in the scene, the two male stars were deemed too important to film such a risky scene and had stunt doubles.

Norman Kerry, who was Vicomte Raoul de Chagny in the silent version, visited the set of the 1943 version and shook hands with Nelson Eddy, as photographs testify.
