CBR: So one of the big motifs in The Casting is this idea of Bats vs. Birds — It’s obviously directly related to a lot of stuff here, Hawkman, the Blackhawks, the Court of Owls — but there’s one set of birds that hasn’t been called out yet. How is the Bats vs. Birds motif going to factor into the Robins, or even the rest of the Batman mythology?
SNYDER: Oh man, let me figure out a way to say this without spoiling. [Laughs] Let’s see… Well, I can say this. We wanted the war of Birds and Bats to be something that goes all the way back to early days of man, and even further than that, to a theological level. It’s almost cosmic in the story.
The idea is that there is a bat thing, in continuity, in DC history, that to me is totemic and could be as big as the things that inspire, like, pantheons and mythology. Or, maybe it’s older and more ancient and scary than that. So, in the way, it’s this thing that argues that the bat is a symbol of not just darkness, but something that works as a messenger from nightmares. It’s a symbol that Batman has actually co-opted to mean the reverse of that, where he’s taken the bat and made it about bravery and facing fear.
So this thing is going to say, “you took my symbol and I’m coming to get it back.” This thing wants to show how Batman is actually going to be the lever it pulls with all the alternate Dark Knights to [reclaim that symbol]. Batman thinks he’s a symbol that inspires people to do better but this thing wants to show that he’s actually something that makes everyone too afraid to ever go out in the light again.
To be really clear, it’s not an “evil Batman” story in terms of Bruce turning evil, but it is a story about evil Batmen where there are these multiple nightmare versions of Batman.
