Trivia / The Climax

• Divorced Installment: The Climax was originally intended to be a sequel to Phantom of the Opera (1943), and was filmed on the same sets as that movie. However, it was ultimately changed to be a standalone story featuring all new characters.
• Recycled Set: The Climax uses the same sets as Phantom of the Opera (1943). (Well, one opera house looks much like another, I suppose.)
