No DCAU Cast, please.
I mean, they're great, but like I say:
1) They've had a good run already (and opportunities for new takes on these characters are a terrible thing to waste), and
2) They may have done a great job in those shows, but they just don't seem right for the All Star Superman versions of the characters. I mean, that's obviously just my opinion, but I don't think it's an entirely unfounded one.
