Does Werther or War and Peace have more acts?
Werther Werther is an opera ("drame lyrique") in four acts by Jules Massenet to a French libretto by Édouard Blau, Paul Milliet and Georges Hartmann (who used the pseudonym Henri Grémont). It is loosely based on the German epistolary novel "The Sorrows of Young Werther" by Johann Wolfgang von Goethe, which was based both on fact and on Goethe's own early life. Earlier examples of operas using the story were made by Kreutzer (1792) and Pucitta (1802).
Hallelujah of Love Living Pictures - "War and Peace" (Russian: "Zhiviye kartiny Voyna i Mir", Живые картины - Война и мир) is a Russian-language musical composed by Russian film music composer Alexey Rybnikov based upon the eponymous novel by Leo Tolstoy. The musical has yet to be produced. Scenes from the forthcoming musical were presented by the Alexey Rybnikov Theatre Company in the musical show Hallelujah of Love («Аллилуйя любви») on the stage of the Moscow International House of Music in September 2012.
