Check out the images (click any image for super high-res) and quotes from Henry Cavill's interview in Empire Magazine for Batman Vs. Superman.
Henry Cavill On Superman:
"We see the reaction of Lex Luthor, and the reaction of Batman. And the reaction of Baman to this god-like being."
"People have begun to fear him. Is he too powerful? Is he, in fact, a tyrant?"
"He's more used to this gig, doing his best to save as many lives as he can. He is no longer frantic. He's no longer a wet-behind-the-ears kind of superhero."
Zack Snyder and Ben Affleck:
Snyder: "Can we really assume Superman will never turn on us?"
Affleck: "Sо it’s аbоut twо hеrоеs whо cаn bе sееn аs hеrоic аnd villаinоus, аnd whеn yоu lооk аt thе dоublе-еdgеd swоrd оf thаt, diffеrеnt pеоplе will cоmе аwаy lооking аt it vеry diffеrеntly."
Affleck: "Rаthеr thаn just Аliеn Vs. Prеdаtоr, whеrе yоu hаvе twо mоnstеrs аnd thеy’rе gоnnа fight, yоu hаvе twо pеоplе whо rеаlly truly bеliеvе thеy аrе dоing sоmеthing hеrоic аnd nеcеssаry in thеir cоnﬂict."
Affleck: "Batman has seen the devastation that comes from aliens battling on Earth. He thinks Superman is attracting flies to our planet. He is basically a beacon."
Henry Cavill on Clark Kent:
"He is the human side of the character, but there is often this idea that Clark and Superman must be so different. He's being himself, only he's presenting a different front while he's in these different outfits. He can only get away with wearing glasses so much. If he's drawing attention to himself by being clumsy, that's not going to work. We don't want to be jokers."
Henry Cavill on Lois Lane:
"It's not a normal relationship. How could it be? One of them is an alien."
Henry Cavill On Batman:
"He doesn't agree with his form of justice. For this farm boy who tries to do things the right way, justice at any cost is not something he can come to terms with."
Cavill notes that instead of Superman bullying Batman by simply defeating him, he uses Clark Kent to "..show the world what this Batman dude is doing."
"It's the human outlook on Superman and that is why such a major thing happens. It's not about one on one. Of course Superman is going to win, but it's deeper than that. It's more that these two great powers exist and are actually trying to achieve the same thing, but in such different ways."
Cavill: "I don't do push-ups. (prefers three hours a day on the on-site gym). Zack does a lot of push-ups on set, though. He started a push-up cult."
Cavill: "It's not as if I am going to be able to play a POW and then Superman again. (Cavill put on 30 lbs). My commitment lies with this first."
Cavill: "He's always in there. It sits there simmering at ten percent all the time and then when it comes to acting, you just crank it up to 100 percent."
Henry Cavill on the Dawn of Justice League:
"There are hero moments where it looks like a hero moment. It doesn't look like a bum saving a bunch of people then disappearing into the shadows. We're introducing a potential long-term villain (Lex Luthor), we're introducing Batman, and we're introducing Wonder Woman. This is the Dawn of Justice."
"It's a bunch of people who are all used to getting their own way, so we'll see how they interact. And the guy who can kick anyone's ass is the nice one."
"Batman v Superman: Dawn of Justice" has a March 25, 2016 release starring Ben Affleck as Batman, Henry Cavill as Superman, Gal Gadot as Wonder Woman, Amy Adams as Lois Lane, Laurence Fishburne as Perry White, Diane Lane as Martha Kent, Jeremy Irons as Alfred, Jesse Eisenberg as Lex Luthor, Ray Fisher as Cyborg with Callan Mulvey, Holly Hunter as Senator Finch and Tao Okamoto as Mercy Graves.

Fearing the actions of a god-like Super Hero left unchecked, Gotham City’s own formidable, forceful vigilante takes on Metropolis’s most revered, modern-day savior, while the world wrestles with what sort of hero it really needs. And with Batman and Superman at war with one another, a new threat quickly arises, putting mankind in greater danger than it’s ever known before.
