Trivia: Phantom of the Opera (1943)
- Executive Meddling: The original screenplay of the 1943 version revealed that Erique was Christine's father. But the execs at Universal were afraid that viewers would think the relationship between Christine and The Phantom had incestuous overtones, so that revelation was cut out.
- Incidentally, it's entirely possible to watch the movie with this in mind, and it makes just as much sense as the canonical unrequited-love plot (since Erique's interest in Christine, unlike his counterparts in other versions, is more of an ambiguous deep concern for her that could go either way).
- Recycled Set: Sets made for the 1925 film were reused.
- What Could Have Been: The film was initially conceived to be a part of the Abbott and Costello series, with Lon Chaney jr. as The Phantom.
