This takes the idea of instead of Iron Man coming out in 2008, Man of Steel did. This starts the DC Cinematic Universe, and it's good. So, I'm, we're, casting it here. Take these actors in their prime, so some aren't dead (*cough cough* Christopher Reeve *cough* Adam West). I've included some animated versions, so feel free to vote for them too. Also, if you don't know where the actor/actress played the character, just search their name and the character's name. And we already know that Tara Strong can play everyone, so don't put her in the running.
