When we actually find out if Nolan did indeed have a grievance and what it was, we'll we able to discuss this more appropriately.
Just asking coz I think if you were involved professionally in some form of art/design business I think you might see things a little differently.
Oh, the oh-so-elite world of "You can't do that, that's my idea"? No one but a TRUE artiste could ever understand that, right?
No, I don't think I would see things differently. I'm not that thin skinned, and in this case, I damn sure understand the nature of adaptation of characters I didn't create or own quite well. If, like Nolan, I didn't own Batman, and WB did, I wouldn't ***** when WB wanted to show people just how cool Batman can be with other superheroes, or wanted to show another aspect of Batman's mythology. What's next, Chris Nolan complaining about THE BATMAN animated series or reruns of JUSTICE LEAGUE?
As someone who is in the art/design business I can see where Nolan would be annoyed, in fact I've had similar things happen to me, not exactly the same, but similar.
There's a difference between actually creating something and someone else taking what you did and passing it off as their own...and helping restart a hero's popularity and having someone else show a different aspect of the hero's mythology. That is what's going on here.
And you know what? Nolan did not create Batman, nor did he create the elements of the Batman mythology that made people like BATMAN BEGINS (gasp, I know, it's true, he didn't come up with that stuff). Again, it's not like WB is forcing Nolan to make his third Batman film "JUSTICE LEAGUE" or "BATMAN AND SUPERMAN". Nolan's Batman will still be able to operate solo, in his own, slightly more realistic world, and no harm, no foul.
Ok, lets say Justice League is a bad film, I'm mean really bad, Batman and Robin bad, there is a possibility that negative reception could flow over to subsequent superhero based films, in spite of how good the predecessors are.
Lets say it is. 1, that is unlikely. And 2, why would people abandon Nolan's Batman franchise over something that isn't related to it? Remember, people came back to Batman without much fuss after BATMAN & ROBIN. Are people now suddenly so stupid they can't tell the difference between movie franchises? If THE DARK KNIGHT is serious, well written and well done, why would people suddenly abandon the sequel, especially if it looks good when the trailers come out?
Having said that however, the reverse could also possibly happen, the film might be so bad that audience will see that Nolan's series as being far superior, thereby reaction may be limited to the JL film only and Nolan's final film could benefit. It's a coin flip situation, it could go either way, the question Nolan is probably asking is why flip the coin in the first place?
I'll be honest. If this is the way Nolan's thinking, and I very much doubt it is, Nolan needs to stop overthinking things so much and just make the best movies he can, and let the chips fall where they may. You don't blame someone else for your film's shortcomings.
Some of you are making so many assumptions it's not funny.
Once again. We don't know the nature of Nolan's grievance, if there is in fact one, but I'm damn sure it isn't "Oh no, how will the financial success of JUSTICE LEAGUE impact a film I haven't even made?"
The ONLY way I could understand Nolan being upset is if he'd planned to use Talia in BATMAN 3. But then, if he's banking on a twist like that to make his BATMAN 3 work, he's screwed anyway.
t: Sadly it will never happen.
