Each "Phantom of the Opera" deviates somewhat from the Leroux novel - with the original silent film with Lon Chaney perhaps being the exception. In the '40s Nelson Eddy version, the police chief and an operatic baritone are Christine's suitors instead of Raoul (though the baritone is named Raoul) and it's hinted that the Phantom is her father. His acid in the face was the result of a misunderstanding at the music publisher's.
In this particular "Phantom," from Hammer Studios, the Phantom (Herbert Lom) has an Igor-type assistant, and here Christine's suitor is the manager of the opera house (Edward de Souza). There is also a real villain, a plagiarist in the form of Lord d'Arcy (Michael Gough). Most notably, it has a production of "Joan of Arc" with music written by Edwin T. Astley that is actually very pretty and beautifully sung.
Everyone does a terrific job in this - Gough is hateful as the supposed composer of the opera; de Souza is a hunk and a good romantic interest for Christine; and Heather Sears as Christine is very sweet and, like all Christines, lacking the diva quality her rival has. In this film, the rival singer is a very minor role. The dubbing of the voices is wonderful.
Herbert Lom, normally a comic character in the "Pink Panther" series, is a great phantom, performed at a time when the Phantom didn't have to be better-looking than the ingénue. The Phantom is not a huge role in this film, but an effective and highly sympathetic one. He seems a little less nuts than some of them, though he's clearly not completely there.
The final scene of this film is very exciting, and the final picture very powerful and sad. This is a really excellent version with not much emphasis on the horror aspects of the Chaney film. It has good production values and is very well directed.
