With the Nolan Bat-flicks still firmly planted in popular consciousness, Wilkinson and Snyder had to find a way to make this incarnation their own:
"The batsuit is a complete 180 degree turn from the previous film incarnations our Batmans power comes from his incredible physical strength and fighting skills, not from armor. The director Zack Snyder wanted him to look as much like the comic book version as possible to be respectful to the original source."
Right from the get-go this Batman's suit has created the illusion of a hardened brawler, something closer in design to the hero of Frank Miller's The Dark Knight Returns (there's that research again) than the stealthier, sleeked night-stalker Christian Bale and Chris Nolan cooked up in their cycle. He'll probably need the extra heft too; Bane might be a toughie, but Superman's a whole other level of physical specimen. Helping with that will be the brass knuckles installed in Batman's gloves. These alone indicate how one costuming decision can totally help redefine a character. Brass knuckles scream brutal street-warfare, which might be more this Batman's style - ditch the theatrics and just plug the bad guys senseless. I'm not sure they'll put a sufficient dent in Superman, but they certainly remove some of the performative polish seen in previous incarnations and infuse the re-design with a thuggish, non-poetic quality.
