- When the film was released in South Korea, it did so much business that some theaters were showing it four and five times a day. One theater owner in Seoul tried to figure out a way to be able to show it even more often, in order to bring in more customers. So he cut out all the musical numbers.

- The main reason the film was not shown inside Germanic Europe is because of the serious historical inaccuracy to both the Anschluß of Austria and the Nazi Party being portrayed inaccurately, just in general. Even before it came out, Hedy Lamarr warned the studio not to show it inside Germanic Europe, because she knew how the men, especially, would react, but the studio executives laughed her off. Several other famous Germanic Europeans also did not take kindly to the film, becoming quite vocal, including: Peter Lorre, who had seen the Broadway play, [?] Marlene Dietrich, Eva Gabor, Billy Wilder, Audrey Hepburn, [?] Werner Klemperer, [?] John Banner, [?] Fritz Lang, [?] Karl Freund, [?] Robert Clary and [?] Erich Pommer. It is what caused the studio to pull the film from cinemas six months before they intended to, causing them to actually lose money on its first release. It was not until the late 1970s when the film would actually break even.
- The day after the von Trapp family left Austria (by train to Italy, not trekking over the mountains to Switzerland as the film depicts), Adolf Hitler ordered the borders of Austria to be shut.
