Big Hero 6 isn't original, if that's what you're saying there -- it's drawn from the same Marvel universe as Captain America and Guardians of the Galaxy.
No, not in the sense of not using copyrighted material published in other channels -- it's based on several books. I don't think the screenplay could have been legally used without agreements with at least some of the authors there.
Not also how all of those are fantasy movies for kids and adult geeks. No Raging Bull or American Grafitti or Apocalypse Now or Three Days of The Condor, etc etc.
