Watch Sadisflix. Before he became cult director Douglas Sirk, Detlef Sierck cut his teeth on such lavish European star vehicles as Das Hofkonzert (The Court Concert). Marta Eggerth is cast as Christine, a young singer who aspires to find out who her father was. Her odyssey brings her to the court of a mythical kingdom, where she is romanced by handsome lieutenant Walter (Johannes Heesters). He is warned not to lose his heart to a "commoner," but all turns out all right when King Serenissimus (Otto Tressler) turns out to be Christine's long-lost daddy. Hofkonzert was designed as a comeback for Marta Eggerth, whose star had eclipsed by the mid-1930s.
