There are two additional elements that I really like but that are somewhat obscure. These two have never worked their way back into the comics and are probably not very popular outside mine own brain.
Ro-Zan
In the Kirk Alyn serial, the Lowther novel, and the George Reeves series, the head of the Kryptonian council of Wisdom was named Ro-Zan. I don't know why, but I just think the name is really cool. I'd like to see it inserted into continuity and for the character to have a bigger role in the "destruction of Krypton" part of the origin. Maybe even give him some back-story.
Ooooh, neat idea! I do recall this character. Further, it's one that is needed; the head honcho that tells Jor-El to shut his trap. Otherwise, the Krypton council is fairly faceless.
Ditto for
...Incidentally, where is it possible to GET the Lowther novel these days?
The Mole-MenSure, the pilot-movie was technically clumsy; but I'd really like to see the Mole-Men return in the comic books. Maybe even have Superman visit their home at the center of the Earth. With the hugely destructive environmental impact that human activity has been having, and with the accelerated rate of change that the entire planet is undergoing, the Mole-Men would be sure to notice. They might even try to do something about it. And if that involved a conflict with humanity, which side would Superman support? A great way to bring back some great characters.
Are you kidding? EVERYBODY loves the Mole Men! They're so cute!
And they can use the name without impunity because it came in the days before the OTHER "mole man" (though Miracleman might have something to say about that). Their society and culture and underground world is something that a comic book, which has a nearly unlimited special effects budget, can show us much more readily than a television show can.
If anybody could do it, I'd put my money on Roger Stern; he was an old school George Reeves fanboy.
And "Crystal Krypton" was such a great, otherworldly look. It was like living inside of a gemstone. And those costumes! The way they seem to glow.
It's a great thing that this aesthetic design is being preserved and updated into the next SUPERMAN RETURNS movie. I'm partial to both "movie" Krypton, with its biblical dialogue out of Cecil B. de Mille, and the Hugo Gernsback Krypton of the Silver/Bronze Ages.
(Though I wasn't crazy about the "christmas ornament" spaceship...couldn't they just make it a rocket, only out of crystal?)
