I believe we're going to get the Batman 89 treatment with how they deal with the new versions origin. Whether they do that in Justice League briefly in the beginning or wait until the first solo film, I don't know. But it's going to happen im sure.
I may as well start a petition for Jane Levy as Harley Quinn, Bryan Cranston as Commissioner Gordon and Michael Madsen for Harvey Bullock. Im very adamant about those choices. Especially those first two. Bullock's casting doesn't really matter in the long run, they can surprise me I guess.
I would prefer it if Joker was brief in the next series, but still a thread in each of the films somehow. I really can't say who should be cast as Joker. Chances are they'll surprise us.
Besides my usual picks for Bruce (Evans, Gosling, Bomer, Fassbender)...I do think that's going to be another surprise casting choice that makes us all take a step back. I have a feeling it's going to be somebody none of us thought of.
Chastain would make for a great Vikki Vale.
I REALLY don't want them to use Lucius Fox in the reboot at all. But the next time we see him, I think Denzel Washington should be the choice. It would have to be a good role though for him to do it, and I don't really want to see that for a long time.
Don't feel like seeing Renee Montoya since Ramirez was kind of Nolan's version. But Rosario Dawson comes to mind for some reason.
I wonder if Sarah Essen would be a character in the reboot? Something new for Gordon's character that we haven't seen. Don't know who to cast for that.
Riddler and Penguin will probably be unconventional choices I think. Same with Black Mask. Hugo Strange? I think of Christoph Waltz.
Then there's Alfred. Ahhh. Sooo many choices.
