Regarding the DC Expanded Universe, Cavill offered everything is connected.
"There’s a big plan in place at WB for the whole DC franchise," Cavill told Uproxx. "So, all of this stuff ties in. They’re not thinking from movie to movie, they’re thinking from a big tent pole type thing and each story has its own story, which is attached to the major issue. Yeah, there’s a big plan."
Henry Cavill also happens to be a big Warcraft fan, so much so that he missed Zack Snyder's initial call in regards to getting the Superman part on Man of Steel because he was playing the game. Cavill offers he used to play the game a lot, and Hammer and Cavill joke about Henry looking forward to Batman Vs. Superman more because Cavill isn't getting paid for Warcraft.
"Yeah, Warcraft isn’t making me any money!" Cavill laughed. "But, yes, BvS, I’m really looking forward to. But with World of Warcraft, I’m excited to see what it’s like because that’s a hard thing to translate, and there are a lot of people who feel strongly about the lore in that, so we will see."
Cavill also went on to confirm a connection between Man of Steel and the Batman Vs. Superman trailer (watch below), which showed heat vision destroying Metropolis with Ben Affleck's Bruce Wayne looking on.
"That’s when Zod loses his mind and can’t control his heat vision and blasts everything out," Cavill confirmed.
"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. Justice League is to follow directed by Zack Snyder as well.
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.
