 Traudl Junge, Adolf Hitlers "last" secretary, was interviewed by  Michael Mussmano several times; part of her recollections were  included in his "Ten Days to Die" from which this film is adapted.  In Junges memoirs, "Until The Final Hour," she says that Mussmano  helped arrange for her to spend two weeks in Austria advising the  director during filming, for which she was paid DM1500.
