Context_1 : The Phantom of the Opera is a 1910 novel by Gaston Leroux. Context_2 : Christine Daae is a fictional character and the female protagonist of Gaston Leroux's 1910 novel "The Phantom of the Opera" and of the various adaptations of the work. Erik, the Phantom of the Opera falls in love with her. Context_3 : There have been many literary and dramatic works based on Gaston Leroux's novel "The Phantom of the Opera," ranging from stage musicals to films to children's books. Some well known stage and screen adaptations of the novel are the 1925 film and the Andrew Lloyd Webber musical (see "The Phantom of the Opera (1986 musical)"); Susan Kay's 1990 "Phantom" is one of the best known novels and includes in-depth study of the title character's life and experiences. Context_4 : Erik (also known as The Phantom of the Opera, commonly referred to as The Phantom) is the title character from Gaston Leroux's novel "Le Fantome de l'Opera" (1910), best known to English speakers as "The Phantom of the Opera". He is also the protagonist and antagonist of many film adaptations of the novel, including the 1925 film adaptation starring Lon Chaney, the 1943 remake starring Claude Rains and Andrew Lloyd Webber's musical. Context_5 : The Phantom of the Opera is a 1925 American silent horror film adaptation of Gaston Leroux's 1910 novel "Le Fantome de l'Opera", directed by Rupert Julian and starring Lon Chaney, Sr. in the title role of the deformed Phantom who haunts the Paris Opera House, causing murder and mayhem in an attempt to make the woman he "loves" a star. The film remains most famous for Chaney's ghastly, self-devised make-up, which was kept a studio secret until the film's premiere. The film was released on November 25, 1925. Context_6 : The Canary Trainer: From the Memoirs of John H. Watson is a 1993 Sherlock Holmes pastiche by Nicholas Meyer. Like "The Seven Percent Solution" and "The West End Horror", "The Canary Trainer" was published as a "lost manuscript" of the late Dr. John H. Watson. In "The Adventure of Black Peter", an original Arthur Conan Doyle Holmes story from 1904, Watson mentions that his companion recently arrested "Wilson, the notorious canary-trainer, which removed a plague-spot from the East-End of London." This Wilson (who figures prominently in the Adrian Conan Doyle pastiche "The Adventure of the Deptford Horror") is not related to the eponymous character of Meyer's novel. Meyer's "trainer" is Erik, the principal figure of Gaston Leroux's 1910 novel "The Phantom of the Opera". It is from this unchronicled tale that The Notorious Canary Trainers (a Sherlockian scion in Madison, Wisconsin, founded in 1969) take their name.
