Question: A film featuring a giant anthromorphic pig was based on an act from what theatrical genre of variety entertainment?
Context: Naka Rabemanantsoa is a pianist and composer of "vakondrazana" and "ba-gasy" music from the central highlands of Madagascar.  He was a major composer for the Malagasy theatrical genre that reached its peak between 1920 and 1940 at the Theatre d'Isotry in Antananarivo.  His pieces were typically written for piano, and although his pieces were often adapted for solo, duet or choral vocal accompaniment sung in the Malagasy language, he was a strong proponent of preserving strictly instrumental accompaniment for theatrical performances.  His songs form part of the canon of classical Malagasy piano music, and a street in downtown Antananarivo is named after him. Féerie was a French theatrical genre known for fantasy plots and spectacular visuals, including lavish scenery and mechanically worked stage effects.  "Féeries" blended music, dancing, pantomime, and acrobatics, as well as magical transformations created by designers and stage technicians, to tell stories with clearly defined melodrama-like morality and an extensive use of supernatural elements.  The genre developed in the early 1800s and became immensely popular in France throughout the nineteenth century, influencing the development of burlesque, musical comedy and film. Vaudeville ( ; ] ) is a theatrical genre of variety entertainment.  It was especially popular in the United States and Canada from the early 1880s until the early 1930s.  A typical vaudeville performance was made up of a series of separate, unrelated acts grouped together on a common bill.  Types of acts have included popular and classical musicians, singers, dancers, comedians, trained animals, magicians, strongmen, female and male impersonators, acrobats, illustrated songs, jugglers, one-act plays or scenes from plays, athletes, lecturing celebrities, minstrels, and movies.  A vaudeville performer is often referred to as a "vaudevillian". Ketoprak (Javanese: Kethoprak) is a theatrical genre of Java featuring actors who may also sing to the accompaniment of the gamelan.  It draws its stories from Javanese history and romances and in this differs from "wayang wong", which shares with "wayang kulit" a repertoire drawn from the Hindu epics Mahabarata and Ramayana, as well as from "ludruk" which uses contemporary settings and the three-walled "srimulat", which specializes in vampire stories.  According to Clifford Geertz it was invented as recently as 1923. The Theatre of the Ridiculous is a theatrical genre that began as an American movement in New York in 1965 with the beginnings of "The Play-House of the Ridiculous", and the spin-off group formed in 1967, "The Ridiculous Theatrical Company". Music hall is a type of British theatrical entertainment that was popular from the early Victorian era circa 1850 and lasting until 1960.  It involved a mixture of popular songs, comedy, speciality acts, and variety entertainment.  The term is derived from a type of theatre or venue in which such entertainment took place.  British music hall was similar to American vaudeville, featuring rousing songs and comic acts, while in the United Kingdom the term "vaudeville"' referred to more working-class types of entertainment that would have been termed "burlesque" in America. Variety shows, also known as variety arts or variety entertainment, is entertainment made up of a variety of acts including musical performances, sketch comedy, magic, acrobatics, juggling, and ventriloquism.  It is normally introduced by a compère (master of ceremonies) or host.  The variety format made its way from Victorian era stage to radio and then television.  Variety shows were a staple of anglophone television from the late 1940s into the 1980s. Le Cochon Danseur (English: "The Dancing Pig") is a silent, 4 minute long, black-and-white burlesque film released in 1907 by French company Pathé, apparently based on a Vaudeville act.  In the film, a giant anthropomorphic pig, dressed in human fancy clothes, dances with a girl, who later embarrasses him by tearing his clothes off.  The two start to dance together, then walk into the curtains behind them.  A disturbing scene is then shown where you see the pig moving his tongue and eyes around and then baring his teeth. Vaudeville was a theatrical genre of variety entertainment in the United States and Canada from the early 1880s until the early 1930s. Avanspettacolo (literally: "before the show") is an Italian theatrical genre that developed between the 1930s and 1950s.  Closely related to revue and variety show, avanspettacolo features a diverse mixture of music, ballet, sketch comedy, and other forms of entertainment.  The genre emerged during the Fascist era, as a consequence of the promulgation of "modernist" laws that granted tax relief advantages to the theatres that were adapted to play movies.  As a consequence, theatre companies were forced to devise a light and short form of representation that could be performed on the stage to entertain the audience before the "main show" (i.e., the movie).
