Please answer the following question: Information: - Vitaphone was a sound film system used for feature films and nearly 1,000 short subjects made by Warner Bros. and its sister studio First National from 1926 to 1931. Vitaphone was the last major analog sound-on-disc system and the only one which was widely used and commercially successful. The soundtrack was not printed on the film itself, but issued separately on phonograph records. The discs, recorded at rpm (a speed first used for this system) and typically in diameter, would be played on a turntable physically coupled to the projector motor while the film was being projected. Many early talkies, such as "The Jazz Singer" (1927), used the Vitaphone system. The name "Vitaphone" derived from the Latin and Greek words, respectively, for "living" and "sound". - Maria Corda (Maria Antonia Farkas, 4 May 1898 in Deva, Hungary (now Deva, Romania) 15 February 1976 in Thonex, Switzerland) was a Hungarian actress and a star of the silent film era in Germany and Austria. - A silent film is a film with no synchronized recorded sound, especially with no spoken dialogue. The silent film era lasted from 1895 to 1936. In silent films for entertainment, the dialogue is transmitted through muted gestures, mime and title cards which contain a written indication of the plot or key dialogue. The idea of combining motion pictures with recorded sound is nearly as old as film itself, but because of the technical challenges involved, synchronized dialogue was only made practical in the late 1920s with the perfection of the Audion amplifier tube and the introduction of the Vitaphone system. During silent films, a pianist, theatre organist, or, in large cities, even a small orchestra would often play music to accompany the films. Pianists and organists would either play from sheet music or improvise; an orchestra would play from sheet music. - In Greek mythology, Helen of Troy (Greek "Helen"), also known as Helen of Sparta, or simply Helen, was the daughter of Zeus and Leda, and was a sister of Castor, Pollux, and Clytemnestra. In Greek myths, she was considered the most beautiful woman in the world. By marriage she was Queen of Laconia, a province within Homeric Greece, the wife of King Menelaus. Her abduction by Prince Paris of Troy brought about the Trojan War. Elements of her putative biography come from classical authors such as Aristophanes, Cicero, Euripides and Homer (both "The Iliad" and "The Odyssey"). - In Greek mythology, the Trojan War was waged against the city of Troy by the Achaeans (Greeks) after Paris of Troy took Helen from her husband Menelaus, king of Sparta. The war is one of the most important events in Greek mythology and has been narrated through many works of Greek literature, most notably through Homer's "Iliad". The "Iliad" relates four days in the tenth year of the decade-long siege of Troy; the "Odyssey" describes the journey home of Odysseus, one of the war's heroes. Other parts of the war are described in a cycle of epic poems, which have survived through fragments. Episodes from the war provided material for Greek tragedy and other works of Greek literature, and for Roman poets including Virgil and Ovid. - The Private Life of Helen of Troy is a 1927 American silent film about Helen of Troy based on a novel by John Erskine and adapted to screen by Gerald C. Duffy . The film was directed by Alexander Korda and starred Maria Corda as Helen , Lewis Stone as Menelaus , and Ricardo Cortez as Paris . Coming at the end of the silent film era , it received the honor of being nominated for an Academy Award in 1929 , the year of the Awards ' inception , in the category of Best Title Writing .

Two sections from the beginning and end , running about 27 -- 30 minutes in total , are reportedly all that survive of The Private Life of Helen of Troy ; they are preserved by the British Film Institute . - Switzerland, officially the Swiss Confederation, is a federal republic in Europe.

This optical illusion causes the audience to perceive continuous motion between separate objects viewed rapidly in succession. The process of filmmaking is both an art and an industry. A film is created by photographing actual scenes with a motion picture camera; by photographing drawings or miniature models using traditional animation techniques; by means of CGI and computer animation; or by a combination of some or all of these techniques and other visual effects. - Zeus ("Zeus", ; Modern , "Dias" ) was the sky and thunder god in ancient Greek religion, who ruled as king of the gods of Mount Olympus.
