I'm not being an ass (for once). I was presenting a situation in which you would accept the joint responsibility for creation, and then explaining how that scenario relates to the reality of Batman's creation.
There was no "joint creation". Your scenario doesn't work, because you are saying that fifty-years of evolution equates to the original creation of the Joker. You are saying that character evolution can be linked to the original thought-process behind the comic-book presentation of the Joker, and how that evolution is well within its rights to destroy any mystical aspect behind the Joker.
Bob Kane and Bill Finger intended the Joker to have no origin story. They wrote the character so that he didn't have an origin story; he is just there, and he is f*****g nuts.
No, because the act of contribution and analysis are not the same. Contribution occurs during production and affects the final work; analysis occurs after production and only affects perception of the the work as it has been produced.
Batman is a joint creation because production never finished, and because Kane volunteered authority over production to others.
But the original "production" of the Joker implied that he had no origin. There was no explanation behind the perma-white skin. He was a character of mystery. I can see the difference between a contribution and an analysis, but it cannot be applied to this instance, because people are analyzing
HOW the Joker ended up with bleached skin. I aren't contributing to it, because the character's origin was never intended to be a means of contribution. The only contribution that the writers sought out was that of the reader -- they left it up to the reader to decide how the Joker ended up with white skin... and the DC execs have tried to blow that straight out of the window by selling the chemical bath origin as an all-encompassing truth, when in reality, it is nothing more than a mere analysis/theory on how the Joker came to be.
The Scream painting is a finished piece of art, but the Joker's characterization was also a finished piece of art, before it was tampered with, and then sold as a "fact" -- until the DC execs tried to rip apart the exact premise of art:
INTERPRETATION.
No, that's not what I meant. Bob Kane doesn't have to agree--he was not interested in agreeing. If he wanted Batman to be solely his work, he would have taken it elsewhere or published in independently.
There is an issue here in that you seem to be approaching Batman as having been a finished work that Kane then presented, and other artists then extrapolated on. This isn't the case. Batman was never a finished work, and is still not a finished work. He was designed--by Kane--to be ongoing, and ongoing without Kane necessarily at the helm.
But the Joker character, in of itself,
was a finished piece of work, in all actuality. The character has no renowned origin; the character is just some crazy guy with white skin. That is all Bob Kane ever intended the Joker to be, I am sure. Sure, you can use that character to present stories -- to present anarchy -- to present different interpretations of the character -- but the main themes and constants will always be intact: he has white skin, green hair, hates Batman and finds crime amusing.
Then, people from DC sought to analyze how the Joker became the Joker. The chemical bath origin may be seen as a contribution, but it is also an analysis -- but hey, I'm simply going by your logic.
In the end, whether or not the Joker is a "finished article" in terms of what the character means and how he acts is a totally different issue, but the main point is that the origin of the character was never meant to be revealed, and the only people who would know of the true origin of the character are the creators, just as the only person who would know what the person is screaming at in the Scream painting is the actual artist. People who try to explain things regarding those pieces of art, regardless of their job title, are, essentially, guessing and analyzing that particular piece of art-work. Ergo, how is that guessing any more valid than my own guessing? I just don't get that. And please don't respond with the "It is DC canon so there is no room for debate" stuff, please -- it hurts my...eyes.
Well, that's just it: he didn't sell Batman to DC. They commissioned it. You call it "his character," but it never was. DC hired him to create a character to capitalize on Superman's popularity, with the understanding that, once created, the character would belong to them. So, he created Batman. You're stuck on this idea that Kane created something that DC took and tampered with, but that simply isn't the case. Bob Kane did not create Batman singlehandedly--he was created by DC, Kane, Finger, and then every artist and writer to come along since then, because the character was not created to be finite. Batman is a work in progress.
DC Comics is just a business group. Bob Kane and Bill Finger are the people who keep DC Comics with its head above water. Again, this "forest for the trees" argument is becoming more and more apparent. Who created the Joker character? Bob Kane and Bill Finger. DC Comics were simply a means to an end.
And in this instance, the "composer" is not Bob Kane--but rather, Kane and scores of other people.
"Creator", then, shall we say? I mean, if you insist that "other people" compose the Joker character, then why do you insist that my own ideas and preferences about the character are not as important as those who have a nifty job at DC Comics? This is the entire debate in a nut-shell. The writers of DC Comics are just ordinary people, like you and me. The only difference being that they are pretty good writers and have a good understanding of comic-books. How their collective interpretation of the Joker's origin is any more valid than my own I do not know. I could write a story about the Joker; acquire myself a successful publisher; and then sell my product. Would I be selling my product as a factual resource for Joker information? Hell no. I'd just be there to entertain people -- to expand the vision of others. To basically publicize my art-work. I'm sure Sunburned Hand would tell you this, too...
