Everet's not bad at all, but I'd pick Jason Isaacs as Metallo. I love the way Alex Ross draws him, based on his first appearance(can't find a pic at the moment, though), and Isaacs could channel that in both look and manner.
Metallo is one of my favourite Alex Ross designs, yeah.
Barrack Obama as Ron Troupe.
It's DREAMCasting. Nobody said they had to be actors...
Seriously, every time I hear an Obama speech, I'm reminded of Ron Troupe. Troupe is described in Action Comics Annual 11 as being "too good for the Planet". So why not have a Presidential candidate play him?
Unfortunately, I can't come up with anything for Steve Lombard.
Vince might be good. He's good looking and manly even if he is a bit hefty and he's the kind of person who could jabber on about anything and expect people to love him for it. The only problem is he wouldn't work unless they recast Lois with someone who wasn't a 3" nine-year old. It would just look weird if he was hitting on her.
TOG's cast is nice although is it okay if I never want to see Lana Lang ever again for at least fifteen years? I really don't think her presence in a piece of Superman media is required for a while at least, as everyone is sick to the back teeth of her from Smallville.
Mickey Rourke is interesting as Bizarro, but it would be weird seeing him play such an intellectually stunted character. If they ever do Bizarro in a movie, I'd like to see him adapted a bit and not just have him as a comedy retard like he usually is.
