Superman is not Hollywood IP. Superman is the creative product of two Jewish-American boys born to immigrant families who created an icon of human potential, of righteousness and justice and service to others, at a time when such Ubermensch ideas were being twisted and used by the Nazis in Germany to dehumanize people like Joe Shuster and Jerry Seigel. They made one of the most recognizable and beloved figures in the last century who remains relevant even now, more than 88 years after his first publication in Actions Comics #1. Hollywood has tried to co-op the character, sure, but it's hardly ever done right by him. But the character has never just been limited to a silver screen.
