Batman v. Superman won't hit theatres until next spring, but that hasn't stopped a plethora of rumors from spreading across the Internet. We've summarized some of the more popular rumors below, including ones that have already been at least partially confirmed by producers and/or actors. Be advised that though not much of the movie's plot has been confirmed, the following contains rumored SPOILERS, Read on at your own risk!
The movie will center on the debate over whether Superman is a superhero or an extreme threat. Detractors will point to Metropolis's destruction in Man of Steel as proof of Superman's capability for great destruction. Both Lex Luthor and Batman see Superman as dangerous and will pursue different means to stop him before another city is destroyed. Batman will pursue diplomatic channels as Bruce Wayne to limit Superman's influence before confronting him, while Lex Luthor will experiment with Kryptonian technology to create deadlier ways of stopping Superman.
Batman's appearance in Batman v. Superman is much different than what we've seen in past Batman films. Ben Affleck's Batman is older and seasoned superhero with decades of experience. Affleck has described his Batman as "weary" and he may have experienced the deaths of multiple Robins prior to the film. Leaked set pictures revealed a gravestone for Dick Grayson (AKA the first Robin) and Jason Todd's death at the hands of the Joker is rumored to be canon for the film as well. Judging from promo pictures of the Batmobile and a scene from the first movie trailer, Affleck's Batman may have a more lenient stance on guns than his comic book counterpart. The Batcave will also appear in the film, filled with mementoes from his past battles, including a tattered Robin costume.
Wonder Woman is also set to appear in the film, but it's unclear how big a role she'll play. Producers have stated that their version of Wonder Woman will be a demi-goddess and the daughter of Zeus. A recent rumor also suggests that she will be an older, immortal character and that there will be photos of Wonder Woman dating back to the 1800s. She may also be a potential love interest for either Batman or Superman.
Other heroes that will appear in the film include Cyborg and Aquaman. Aquaman will have a scene with Superman in the film, confronting him over the damage to the ocean caused by the Kyptonian attack in Man of Steel. Cyborg's role is much smaller and will only appear as a small cameo in a film ending montage. Neither Flash nor Green Lantern will appear in the movie.
As stated above, the movie's three main villains are rumored to be Lex Luthor, Metallo, and Doomsday. LexCorp is being depicted as a hip, edgy company in line with Facebook or Google. Luthor will use Kryptonian technology to create both Metallo and Doomsday. Luthor's battle suit may also make an appearance in the film. Tao Okamoto will play
Mercy Graves, Luthor's deadly bodyguard/assistant.
Scoot McNairy is rumored to play Metallo in the upcoming film. Metallo will be kryptonite-powered and there's a scene where Clark Kent discovers his weakness to kryptonite when confronted by Metallo out of costume.
Doomsday's appearance is less certain, but he's rumored to be the villain that unites Batman and Superman at the end of the movie. One rumor suggests that Michael Shannon, who played Zod in Man of Steel, will voice Doomsday and that Lex Luthor will somehow create Doomsday from Zod's corpse.
KGBeast will appear as a minor antagonist in a scene that introduces Batman. However, no other Batman villains will directly appear in the film.
Director Zack Snyder drew heavily from Frank Miller's The Dark Knight Returns when making the film and fans of the comics will notice several movie elements ripped straight from that comic. Batman's costume is almost identical to his appearance in The Dark Knight Returns.
WB is also using the movie to really jumpstart their wider DC Cinematic Universe. In addition to the appearance of several Justice League members, there will be tons of references to different parts of the DC Universe, including many Batman villains and hints of other heroes such as the Blue Beetle or Martian Manhunter.
