Hartnett up for "Superman"…again?

Today’s Comic book adaptation update. Julianne Moore has been spotted about the "Spider-Man 2" set. Might "The Hours" star be up for a cameo?. In addition, Variety reports that Josh Hartnett could indeed be asked to play "Superman" again. "Josh Hartnett recently turned down Warner Bros.’ "Superman" because he didn’t want to be shackled for the next decade with the baggage that comes with that role — even though, in a best-case scenario, he could have earned near $100 million for three pics (assuming that they’re mega-hits). Hartnett could change his mind, as WB will surely reapproach him after the studio enlists a director". Thanks to Superhero Hype
