Okay. I think I've thought of my Superman TV show cast:
Superman/Clark Kent: Matt Long. I know Long looks a little young, but he's about 26, and the show would Have Clark fresh out of Grad school.
Lois Lane: Erica Durance. Hell, she plays the part well, and is one of the better parts of Smallville (even though Lois shouldn't be there in the first place).
Perry White: Hugh Laurie. I loves me some Hugh Laurie.
Lex Luthor: Michael Rosenbaum. He plays Lex well on Smallville, is about the right age for the interperitation I have in mind, and it wouldn't be a rehash of the same preformance, since the Lex interperitation I have in mind is more along the lines of the Lex we saw in Lex Luthor: Man of Steel mixed with Ozymandias from the Watchmen. He's the hero who's willing to do absolutely terrible and monsterous things for what he believes to be the greater good. It's an interpretation of Lex that is very fascinating and, I must say, is a good deal scaryer than a regula mad scientist or corrput buisnessman.
Jimmy Olsen: Shia Leboufe. Shia's like, cool. And stuff.
The Parasite: Adam Baldwin. Watch Firefly. Jayne is basically Rudy Jones in the future with guns.
Metallo: James Marsters. I must admit, I consider James for alot of stuff. But he's really that good. He could pull off the educated and sophisticated street thug very well.
Riot: Mark Hamill. Mark can play crazy, and I just think the fella should get more work.
Atomic Skull: Ron Pearlman. A dillusional psychopath with radioactive powers who believes himself to be the hero of an old 40s movie serial and Superman to be the villain of said serial? Interresting casting challange. A big dillusional psychopath with radioactive powers who believes himself to be the hero of an old 40s movie serial and Superman to be the villain of said serial? Call Pearlman.
Brainiac: Alan Tudyk. Can he play cold and calculating? Yup. Can he play a guy with a quirky sense of humor? Yup. Can he play crazy? Yup. Does he need work? Hell yeah.
Mxyzptlk: Jason Lee. Because, really, he can play a character with Mxy's sense of humor quite well. And because I can't think of anyone else.
