Every time a director helms a new superhero project they put their own spin on that hero's origin story, but no matter how far they stray from the source material they still include some nod to the original.
Action Comics #1 features the most iconic cover art of all time- Superman lifting a car, a scene featured in 1978's Superman and Bryan Singer's Superman Returns, which is an homage to Richard Donner's original Superman films from the 80s.
But the cover of Captain America Comics #1, featuring Cap punching out Hitler, is arguably just as famous, so why didn't it get a proper recreation in the Captain America movie?
Because the writers and director of 2011's Captain America: The First Avenger chose Red Skull and Hydra as Cap's main foes, so including Hitler and the Nazis would just confuse the plot of future Marvel movies.
