[on updating the Superman suit for the sequel] There are some subtle differences in the belt, the buckle and the glyph (shield). Zack loved the idea that there is some Kryptonian script embedded in the suit (at the point where the deltoid meets the bicep). He gave me this fantastic quote that he wanted us to translate into the Kryptonian script and incorporate into the suit. The quote deals with the nature of power and the responsibility that comes with it.
