Question: What opera was written by the first composer of international stature to write Hollywood scores?

full_context: Document 1: Erich von Stroheim: Erich von Stroheim (born Erich Oswald Stroheim; September 22, 1885 – May 12, 1957) was an Austrian-American director, actor and producer, most notable as being a film star of the silent era, subsequently noted as an auteur for his directorial work. He died in 1957 in France, at age 71.
Document 2: Violanta: Violanta is a one-act opera by Erich Wolfgang Korngold. The libretto is by the Austrian playwright Hans Müller-Einigen. It is Korngold's second opera, written when he was only seventeen years old.
Document 3: Tales from the Vienna Woods (play): Tales from the Vienna Woods (1931) is the most famous play by Austro-Hungarian writer Ödön von Horváth (1901–1938). It was premièred in Berlin in 1931 and has been filmed several times. Before the première, the German writer and playwright, Carl Zuckmayer nominated the play for the Kleist Prize, which it won, the most significant literary award of the Weimar Republic. The play's title is a reference to the waltz, Tales from the Vienna Woods by Johann Strauss II. Horvarth's play premièred at the Deutsches Theatre, Berlin. Written in the late 1920s during the period of catastrophic unemployment and the Great Depression, the play is a key work of modern drama, described by Erich Kaestner as "a Viennese folk play accompanied by Viennese folk songs". It is a bitter satire about the mendacity and brutality of the petite-bourgeoisie, named ironically after the forested highlands near the Austrian capital that are so idealised in the waltz. In the play, Viennese 'Gemütlichkeit' or 'coziness' becomes a hollow phrase; the tragic, brutal story of the sweet girl Marianne and the deeply conventional butcher Oskar reflects the hardships and anxieties of the late 1920s during the global economic crisis.
Document 4: Blond Eckbert: Blond Eckbert is an opera by Scottish composer Judith Weir. The composer wrote the English-language libretto herself, basing it on the cryptic supernatural short story "Der blonde Eckbert" by the German Romantic writer Ludwig Tieck. Weir completed the original two act version of the opera in 1993, making "Blond Eckbert" her third full-length work in the genre. Like its predecessors, it was received well by the critics. She later produced a one act "pocket" version of the work. This uses chamber forces rather than the full orchestra of the two act version and omits the chorus. The pocket version receives frequent performances, especially in Germany and Austria, while the full version is available in a recording featuring the original cast.

He was especially noted for his free-hand conducting style that spurned the traditional baton and for obtaining a characteristically sumptuous sound from the orchestras he directed.
Document 6: Königskinder: Königskinder (German for "The King's Children") is a stage work by Engelbert Humperdinck that exists in two versions: as a melodrama and as an opera or more precisely a "Märchenoper".

Strauss was also a prominent conductor in Western Europe and the Americas, enjoying quasi-celebrity status as his compositions became standards of orchestral and operatic repertoire.

Document 11: Euryanthe: Euryanthe is a German "grand, heroic, romantic" opera by Carl Maria von Weber, first performed at the Theater am Kärntnertor, Vienna on 25 October 1823. Though acknowledged as one of Weber's most important operas, the work is rarely staged because of the weak libretto by Helmina von Chézy (who, incidentally, was also the author of the failed play "Rosamunde", for which Franz Schubert wrote music). "Euryanthe" is based on the 13th-century romance ""L'Histoire du très-noble et chevalereux prince Gérard, comte de Nevers et la très-virtueuse et très chaste princesse Euriant de Savoye, sa mye.""
