Of course, if Brad Bird claims that he’s still in a very early stage of writing the script for the new film, we don’t know how likely it is that those rumors were true. They sounded pretty detailed, which would be weird in the context of the director’s claims that he’s still only a few pages in and hasn’t done a large part of the script writing so far.
Still, it could be an actual idea that got leaked by one of his acquaintances, and while that would be unfortunate for Brad Bird, it’s still interesting for his fans to see what kinds of thoughts he has in his head about the film.
We can only wait for more information about this point, and we likely won’t get it anytime soon as the film still has a long way to go in its production. But as soon as Brad Bird – or anyone else involved in the production – decides to reveal more, this is guaranteed to be all over the news as many people are waiting for information right now.
