Phantom of the Opera is a 1925 horror film based on the Gaston Leroux novel The Phantom of the Opera in which a disfigured phantom haunts the Paris Opera House, trying to force the people who run it to make the woman he loves a star. It stars Lon Chaney, Mary Philbin, Norman Kerry, Arthur Edmund Carewe, Gibson Gowland, John St. Polis and Snitz Edwards.

The movie was adapted by Elliott J. Clawson, Frank M. McCormack (uncredited), Tom Reed (titles) and Raymond L. Schrock. It was directed by Edward Sedgwick (uncredited), Lon Chaney (uncredited) and Rupert Julian.

The restored print is a 1929 re-release version that was re-edited, eliminating some scenes and inserting new material shot after the 1925 version was finished. These included a sound sequence with opera star Mary Fabian singing in the role of Carlotta. In the re-edited version, Virginia Pearson, who played Carlotta in the silent 1925 version, is credited and referred to as "Carlotta's Mother" instead. The film has been deemed "culturally significant" by the Library of Congress and selected for preservation in the United States National Film Registry.
