“Fantasia” – “Flight of the Valkyries”
Back when Disney thought that “Fantasia” was going to be an ongoing big hit (instead of the one-off costly flop that it ultimately became), animators prepped out a scene based on Richard Wagner’s iconic “Flight of the Valkyries” composition. This was ultimately canned because Walt Disney was afraid of its connotations— Wagner was a horrible racist, and “Flight of the Valkyries” not only appears in the deeply offensive movie “Birth of a Nation” as the theme of the KKK, but was also synonymous with Nazi propaganda. Probably best to leave this scene on the cutting room floor.
