Also the fact that he had the whole square jaw and big build thing going on (his build was just right - not over-the-top Schwarzenneger big, but big enough to be Superman). In fact, he was so big that it was hard to believe him as a weedy geek when he was in his Clark Kent gear.

Now, I'm not too hot on the continuity of the Superman comics, but according to the Dean Cain TV show (which is probably not the best source) and an old comic I had as a kid that retold his origin, Clark's mother made the suit for him (she noticed that fabric near to his body did not get damaged). Is this the official DC line? If so, how the hell did Clark's mom mould a rubber suit for him? (I asked myself the same question when watching Spiderman, expecially given the fact that you saw Peter's first attempt at making a costume during the wrestling match).
