Austrian Elisabeth von Trapp is considered the mother of the Von Trapp Family Singers, who took their name from her uncle, Austria’s self-proclaimed Father of Lies, Franz Josef.

Austrian actress Franziska von Trapp stars in Georg August’s film . What was it like for her to make such a film? “The film was very sensual, it was very tough for me to make,” she told SheKnows Movies. “It was rough – not really cinematically too hard; [but] emotionally it was so tough. My film was about [my son] Georg who [on] the day of the revolution [was] just a little boy, and then next day he was already running to defend his father.”

With Franziska von Trapp, she portrays her son’s mother in the film. However, before she got into acting, she was a student at Vienna’s Graz Academy of Music.

One of her major inspirations: “My favorite singer was Louise Frahm, who is Hungarian.” She also added, “But as a person, I think being mad was a huge inspiration.”
