Regietheater (German for director's theater or producer's theater) is a term that refers to the modern (mainly post-World War II) practice of allowing a director (or producer) freedom in devising the way a given opera (or play) is staged so that the creator's original, specific intentions or stage directions (where supplied) can be changed, together with major elements of geographical location, chronological situation, casting and plot. Typically such changes may be made to point a particular political point or modern parallels which may be remote from traditional interpretations.

Symptoms of Regietheater may include:

It can be argued that Regietheater began with the work of Wieland Wagner (1917–1966), who in the years after WWII responded to the profound problematisation of his grandfather, Richard Wagner's, work that resulted from its earlier appropriation by the Nazis by designing and producing minimalist and heavily symbolic stagings of Wagner operas in Bayreuth and elsewhere. Guided by the theories of Adolphe Appia, Wieland Wagner's productions allegedly sought to emphasise the epic and universal aspects of the Wagner dramas, and were justified as being attempts to explore the texts from the viewpoint of (often Jungian) depth psychology. In practice this would mean, for example, that the opening act of Die Walküre (the second work of the Ring cycle), specifically described as set in Hunding's forest hut, was presented on a stage shaped as a large, sloping disc: no hut was either seen or implied, and the composer's many detailed instructions relating to the actions of Wehwalt, Sieglinde and Hunding within the hut were disregarded because it was said that the details of the scoring meant that they were already illustrated musically.

Bruno Ganz (German pronunciation: [ˈbruːno ˈɡants] ( listen); born 22 March 1941) is a Swiss actor, known for his roles as Damiel in Wings of Desire and Adolf Hitler in Downfall.

Bruno Ganz was born in Zürich to a Swiss mechanic father and a northern Italian mother. He had decided to pursue an acting career by the time he entered university. He was equally drawn to stage and screen but initially enjoyed greater success in the theater.

In 1960, Ganz landed his first film role, in Der Herr mit der schwarzen Melone (The Gentleman in the Black Derby). Despite the support of lead actor Gustav Knuth, his cinematic debut was not particularly successful and it was only many years later that his career in film got off the ground. Ganz made his theatrical debut the following year and devoted himself primarily to the stage for almost two decades thereafter. In 1970, he helped found the Berliner Schaubühne ensemble and two years later performed in the Salzburg Festival premier of Thomas Bernhard's Der Ignorant und der Wahnsinnige, under the direction of Claus Peymann. The German magazine Theater heute (Theater Today) solidified Ganz’s reputation as a stage actor by pronouncing him Schauspieler des Jahres (Actor of the Year) in 1973. One of Ganz's most physically demanding stage portrayals was the title character in Peter Stein’s 2000 production of Goethe's Faust (Parts I and II), as he suffered injuries during rehearsals and his assumption of the role was delayed.
