So Catwoman and the Schumacher films are part of Earth-89?
I mean, DC didn't cut him saying that in the video (like they would with false/unsolicitated information) so it has to be official.
Schumacher was already confirmed, but reaffirming that isn't bad at all.
It just makes sense. Not because they're all terrible movies, only Batman & Robin has that in common with Catwoman, but the lore of Batman Returns feels like it's expanded upon in the Catwoman movie.
The origin and the photo works too well to be an Easter Egg. They must have wanted to tie into the Batman Anthology at the time.
Why else would they have created a new character to be Catwoman unless Selina Kyle already existed?
Why else would they have Catwoman die like Selina Kyle looked like she had (because originally she didn't die before this movie may have retconed it) before gained cat powers?
Why would Patience Phillips act like a cat like Selina Kyle did in Batman Returns?
Why would Selina Kyle from Batman Returns be considered a previous Catwoman in the continuity of the film?
It feels too coincidental. This video just tops it off giving a level of officiality to what essentially boils down to a perfect easter egg.
Unlike ET and Star Wars, for example, which is too separate with a glaring contradiction, it just works.
