[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.
[on designing the new Batman suit] Zack said that the most important thing for our Batman is that he come across as a really hulking big guy who's super pumped up. He's going to be even bigger than our Superman in silhouette. His strength is not through armor and gadgets, he's basically a tower of muscle. Zack is a huge fan of Miller's The Dark Knight Returns. And we looked a lot at that silhouette when we were creating our silhouette. The cowl I am super proud of. There's always been this huge thing about can he actually turn his head. It does allow full range of movement and he can do all his stunts in the cowl.
