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.
The music during the film's performances was provided by an orchestra. At the premiere, this was conducted by Richard Strauss himself. The film's projection speed had to be adjusted by the projector in order to fit the speed of the orchestra. This task fell to the film's camerman, Hans Androschin, because only he knew the exact length of each scene and cut. In later performances, a special recording, also conducted by Strauss, provided the music. A planned tour of the United States in 1927 by Strauss and his orchestra failed to go ahead because of the emergence of sound films.
