An interview with Batman v Superman: Dawn of Justice costume designer Michael Wilkinson has revealed the motivations for their design, as well as concept art. Speaking with DC All Access, Wilkinson said director Zack Snyder had a specific vision for the costumes, including making Superman’s feature alien-like textures. “This costume was created on another planet with alien technology,” Wilkinson, adding that there are differences in the belt, buckle, and even Superman’s iconic glyph. “Zack loved the idea there was actually some Kryptonian script embedded in the suit but he gave me this fantastic quote that he wanted us to translate into Kryptonian and incorporate into the script.
