Also, do you remember when Superman: The Movie and Superman II were made? 1978 and 1979 definitely happened before 1985.
Yes, they predated that year. Knowing that doesn’t make them better films. In my opinion, they still fall flat as films independent of Clark’s/Superman’s characterization.
And I’m also curious as to the way in which the things you’ve mentioned treated this subject. How was Clark Kent portrayed differently from Superman in these? etc…
Clark wasn’t clumsy, bumbling, cowardly, etc. He was assertive, competent, and athletic. Basically, he is who his parents – Jonathan and Martha Kent, that is – raised him to be.
