It's possible that he's obligated to avoid specifics because of whatever non-disclosure agreement he signed in the settlement, and is just trying to maneuver around that to the extent that he can. I gather that NDAs like that are pretty common in business.
He's mentioned an NDA before but I can't imagine what kind of NDA would prevent him from making more specific allegations but still permit him to say as much as he already has. And if he truly believes that holding these people accountable is worth burning his whole career down, why should an NDA stop him? Shouldn't he have a moral duty to let everyone know the exact extent of their abuse & racism?
I don't doubt that Joss Whedon is an asshole. But regardless of what he's done, I'll still go to my grave calling him the greatest storyteller of the last 25 years. And before we cast him out as a pariah, never to be allowed to create mainstream entertainment again, I think it's essential that we have SOME idea of what he did to ensure that the punishment fits the crime. I'm not even asking for evidence; just a concrete accusation.
"Despite Walter's best efforts, the Justice League investigation was able to expose the racist, coercive, discriminatory, and retaliatory behavior of Geoff Johns during his tenure with Warner Media's affiliates."
Ummmm, what has actually been exposed? We still know nothing about what they actually did; just that Fisher didn't like it.
Well, Patty Jenkins didn't like Whedon's Justice League, that has very little to do with Whedon's behaviour on set.
Those who did come out against Whedon's behaviour, that I can remember, were Jason Momoa and Gal Gadot.
I've heard about Gal Gadot's incident. But I haven't heard Momoa say anything except that he stands with Fisher and that Snyder's version of the movie was way better than what came out in theaters.
It's actually fairly common for director's-cut releases to include the theatrical cut for comparison, at least in the deluxe sets. I've seen it done in several cases, including Ridley Scott's Legend, Alex Proyas's Dark City, and most relevantly, at least one release of Superman II: The Richard Donner Cut. And I don't see that many movies on disc, so there are no doubt far more examples than I can recall offhand.
After all, the main selling point of a director's cut is that it's an alternative to the primary version, a chance for viewers to see how the director's original "vision" differs from the official release. So it makes perfect sense to include the official release to make it easier to compare the two. The idea that they'd want to suppress the comparison, to pretend the theatrical version doesn't exist, makes little sense. Especially in this case. The Snyder Cut is not replacing the theatrical Justice League. The theatrical version is still the canonical one in the DCEU. The official line, so I've heard, is that the Snyder Cut is an "alternate universe" version.
I've seen lots of cases where only the director's cut or extended cut gets released on blu-ray without the accompanying theatrical cut--
Daredevil, Embrace of the Vampire, Ghost Rider, Troy, Underworld, Watchmen, 2 out of the 4 versions of
Alexander. And given that there were people involved with the theatrical cut of
Justice League that are not involved with the Snyder cut (i.e. Whedon & Johns), I suspect that any blu-ray release of the Snyder cut will not include the theatrical cut if only so they don't have to pay them.
The only time I've seen the original theatrical cut of
Superman II on blu-ray is as part of the big anthology box set (and I'd really rather not have to breathe the same air as
Superman IV, thank you very much).
As for how the Snyder cut will fit into continuity, I think that will depend a great deal on how it's received by the fans. If it's universally praised, I think that it will become the new definitive version and the theatrical cut will be thrown down the memory hole. But if it's greeted with the same mixed reception as
Man of Steel and
Batman v. Superman, I think that they'll just tap-dance around the whole issue until
Flashpoint rewrites continuity to the point where the question is totally irrelevant.
And this comment just made me laugh harder than the entirety of the Flintstones movie.
