Adolf Hitler was enthusiastic about Schiller's play, quoting it in his "Mein Kampf," and approving of a German/Swiss co-production of the play in which Hermann Göring's mistress Emmy Sonnemann appeared as Tell's wife. However, on 3 June 1941, Hitler had the play banned. The reason for the ban is not known, but may have been related to the failed assassination attempt on Hitler in 1938 by young Swiss Maurice Bavaud (executed on 14 May 1941, and later dubbed "a new William Tell" by Rolf Hochhuth), or the subversive nature of the play. Hitler is reported to have exclaimed at a banquet in 1942: "Why did Schiller have to immortalize that Swiss sniper!"
