Even though its just a story, book, movie, etc. how can anyone not see that CK and Supes are not the same person when neither of them wears a mask? Not even CK's glasses are enough to "hide" Supes face. There for 35 years of my life I've always wondered how the people of Smallville and Metropolis can be that dumb. You have people working at the Daily Planet who take pictures and do stories on Superman while Clark Kent is working there. Certainly someone would say "Hey! Superman looks like Clark Kent" and vice versa. Even though its just a movie, how can people be this dumb?
