Although Kevin Smith thought he was being the cagey goalie by bleeping out the name of the artist he thought the new Batman costume was based on Comicbook.com claims one of their commenters was at the live show where Kevin Smith revealed the news about the photo of Ben Affleck he'd seen from Zack Snyder.
"I saw the costume, more than that I saw him [Ben Affleck] in the costume...I don't want to give anything away cause that is up to them and stuff, but I am going to say this...I instantly bear hugged him. You have not seen this costume in film before. Because every other movie has done this matrixy black armor thing...There wasn't a single nipple on this [frick]ing suit man. I think everyone is gonna be like 'Holy Shit!' We haven't been down this path before. Even the Hardest core "[frick] this movie" person will be like 'alright, I'm ready!'
according to comicbook.com though
Of course, Jim Lee has drawn a couple different looks for Batman over the years. He drew the New 52 Batman, which is a black and grey suit. He’s also drawn a classic blue and grey costume design in the past. Whether the cape and cowl will be blue or black is still up in the air, but it definitely sounds like Batman will have a grey suit instead of a black suit.
So which do you prefer?
