Give the emphasis that Tony's family background figures into the IRON MAN film-universe, I found it interesting that many IRON MAN comics from the Silver Age on barely even mention anything about said family.
Now, I had to stop collecting comics in the late nineties, so I don't know how the IRON MAN feature developed. My question: did any comics writer lay the groundwork for the conflicted version of Tony that appears in the movies? I have to say that even when he goes through his alcoholism phase during the Micheline run, that still doesn't seem to play into his parental conflicts.
I see from this essay that CIVIL WAR set up the situation about his parents being killed, but that's not so much about the intrinsic family drama.
