I saw that bit on IMDb as well. Topher Grace would be an interesting Jimmy Olson, but I could do without Mischa Barton as Lois Lane. She's been so overexposed in the media lately that I'm getting a bit tired of her. Now her OC castmate? Hmmm...
As for Brandon Routh...
Reminds me of a younger James Caviezel who was campaigning pretty heavily for the role as well. I guess they're doing the same thing that Warner is doing with Batman... younger, maybe some backstory. Who knows?
