Like pretty much any superhero movie, no one knows who spiderman or Clark Kent are. In the first spiderman movie, at the very end he "gets the girl" but has to walk away from her, because of his obligation to help the world and keep the girl out of trouble. So his sacrifice is known by the movie audience, but not the in-movie characters.
