I wrote this in the casting thread:
This is where I re-invent Clark Kent to a point. I re-invent Clark Kent as more of a true, 21st century-esque "nerd/geek". The witty, dramedy style humor, pop culture knowledge, being a natural klutz just because as Clark Kent he does have to watch what he does physically. Realistically speaking, Clark never would have been able to play sports or really get involved as teen, which is why I always hate incarnations that showed him as some Smallville High stud. He always would have had his guard up, akwardly trying not to stand out. Clark would have turned to activities like writing, hence Journalism, and other "nerdy" nuances. It makes sense this way.
As for Clark Kents look, ditch the over-sized doofus glasses from the movies and apparently Smallville now. It's just cheesy in 70's camp way. One thing Smallville did that I loved was the normal glasses Clark wore in an episode during season 3. I'd go that route. The glasses could be dark rimmed, but normal sized and normal looking. My Clark Kent would wear his hair down. Neat, but down. It's illogical for his hair to be off his forehead as both Clark and Superman. As for clothes, button downs and polo shirts tucked into khakis will do, in any color EXCEPT red, blue, or yellow.
God, I can't go through stumblin, bumbling, campy Clark again. The older I have got, the harder it is to watch that Clark in the movies. Although I would have Clark show up on his first day at the planet stuffy and overdressed, in which Jimmy would make a remark along the lines of "get this man a fedora".
