Well its a dream cast, right. hahahaha! I know its not gonna happen. Hell! I mean if it were truly up to me, I'd have Michael Keaton as Batman still and maybe even have him do a dual role as The Joker. Or I'd get Christian Bale to play Joker cuz I think he'd be an amazing Joker as well. Point is, I don't think about what would be likely. I just visualize how people would act off of each other.

Great list. Lot of casting choices not likely due to existing contracts but lots to like there. You'd think the WB/DC plants would take notes.
The villainy you teach me I will execute-and it shall go hard but I will better the instruction.

I agree. He's usually a highlight in every role I've seen him in.
I've been suggesting Cuthbert for years and still stand by it.
No I'm really not. I think she's a generally bad actress.

Lot of good choices as well. The stand out for me was Garret Dillahunt as Captain Cold. I truly think he is one of the more underrated actors out there. He would do great in almost any role. I also wasn't expecting a Cuthbert inclusion, that caught me off guard in a good way.
I see someone is not a fan of Ms. Robbie though.

Thanks
Would like to see your choices, if you have the time. I also have been trying to create individual character casting lists so that they might become polls users can vote. If you have any suggestions it would be appreciated.
http://www.imdb.com/list/ls061658890/

You got a few real nice choices, even a couple I have chosen myself.
I really like your choices for Catwoman and Deathstroke.

Made it awhile ago but here are my choices

I like your choices for Hatter and Scarecrow

I can't see De Niro in a Batman movie. also why would you "re-commit" the sin of Nolanverse and make the Al Ghuls into white people?
.and then the bong hits him on the head and he falls RIGHT over the realitY

Thank you.
