Der Rosenkavalier is a 1926 Austrian silent film of the opera of the same name by Richard Strauss (music) and Hugo von Hofmannsthal (libretto). Directed by Robert Wiene, it premiered on 10 January 1926 at the Dresden Semperoper, which had also hosted the actual opera's premiere 15 years earlier. Hofmannsthal considerably changed the storyline for the film version and Strauss' score included music not only from the opera but also sections of his Couperin Suite and a march for the Field Marshal, who appears in this version.
