MCU: 10 Fascinating Facts Behind Captain America: The First Avenger (2011)
8. The Nazi Elements Were Toned Down At The Last Minute
Until deep into the movie's pre-production, The First Avenger was supposed to place a far greater emphasis on Nazi iconography, particularly in relation to H.Y.D.R.A.
Though the organisation is still said to be a Nazi deep science division in the final movie, originally H.Y.D.R.A.'s link to Nazi Germany and Adolf Hitler was far more overt, with the film depicting them as a less ambiguous Nazi paramilitary outfit who would even adorn their uniforms with swastikas.
While it doesn't take a particularly deep reading of the movie to appreciate that H.Y.D.R.A. is more or less a stand-in for the Nazis, up until shortly before shooting began, this was set to be much more blatant.
Optics and imagery-wise it was probably for the best, even if it does seem a teensy bit cowardly. After all, wouldn't we all love to see Cap punch a card-carrying Nazi in the face?
