"Now I don't want to give anything away, because that's up to them and stuff, but I'm going to say this - I instantly bear hugged him [Snyder]," he said.
"You have not seen this costume, in a movie, on film before. And for a comic book fan, it was mind-bending. I was like 'Get out of here, only you have enough power to pull this off'. Because every other movie does this Matrix-y, X-Men black armour thing," he continued.
"There wasn't a single nipple on this f***in' suit, man. It was fantastic," self-professed superfan Smith shared.
"I'm already, of course, a flag-waver for the movie, but the costume blew my mind," he added.
"I think you'll be happy, everyone will be like, 'Holy s**t'. It's its own thing; we haven't been down this path at all. Even the hardest core 'frick this movie' person will be like 'alright, I'm ready.'"
Smith then bleeped out a segment of the podcast where he speculated on what influenced the design of the suit.
"It seemed like it was very [Bleep] influenced," he noted.
George Clooney, who starred as the caped crusader in Joel Schumacher's critically-maligned Batman & Robin, recently commented on the rather anatomically-conscious costume he wore in the 1997 sequel.
He was kept in the dark about those moulded nipples.
"The Batsuit was uncomfortable for all of the world. Even little kids come up and kick me," he dished to MTV while promoting Gravity. "They put nipples on the damn thing. You know, I didn't even know it until the film came out."
Clooney also weighed in on Affleck's contentious casting as Batman.
"I am the least qualified person to comment on anyone playing the role of Batman since I so terribly destroyed the part," he quipped to Empire magazine (via The Playlist).
"I tend to look at it like this - let's just see what the movie is before everyone starts beating him up. He [Affleck] is a smart man, he knows what he is doing."
The Man of Steel sequel, tipped to be called Batman vs. Superman, is slated to hit the big screen in July 2015.
