This classic horror feature stars Lon Chaney in the title role as the tragic disfigured Erik, who haunts the corridors and cellars in the decaying depths of the Paris Opera House. He befriends and secretly coaches a beautiful aspiring understudy named Christine (Mary Philbin), who covets the lead role. Through an ever-building campaign of terror, the Phantom drives the lead Soprano to flee her role, allowing his protégé to take her place. Convinced that she will now return his love in spite of his disfigurement, he persuades her to join him in his subterranean lair, where he plans to confess his true feelings.
