Warner Bros. is making moves on Batman vs. Superman.  The studio just announced that Fast & Furious star Gal Gadot will be playing Wonder Woman opposite Ben Affleck’s Batman and Henry Cavill’s Superman in the film, and now it appears they have their sights set on casting the pic’s villain.  Though the working title would lead us to believe that Batman and Superman’s relationship will at one point be contentious, the film will also have a proper villain.  Now that Wonder Woman is set, director Zack Snyder can focus on casting that role, and one of the contenders is reportedly Callan Mulvey.

Hit the jump for more, including which Justice League members will be making cameos in the film.

Embedded in their story about the Wonder Woman casting, Variety reports that Callan Mulvey is “someone Warner Bros. is eyeing” to play the antagonist in Batman vs. Superman.  The New Zealand actor had a small role in Zero Dark Thirty, but he has larger roles in the upcoming sequels 300: Rise of an Empire and Captain America: The Winter Soldier.  The nature of the villain in Batman vs. Superman is being kept firmly under wraps, and will probably stay that way for quite some time if Snyder’s approach to not revealing Man of Steel’s General Zod presence is any indication.

Rumors have swirled recently that Doomsday might be the Big Bad in Batman vs. Superman, and the character would certainly make for a formidable opponent that would necessitate Batman, Superman, and Wonder Woman’s talents.  In the comics, Doomsday is basically a force of nature.  His origins lie in prehistoric Krypton, where he was left to fend for himself as a humanoid infant by an alien scientist.  After being repeatedly killed by the harsh Krypton environment, the scientist continued to clone his genes until Doomsday became an evolutionarily perfect killing machine.

Again, the Doomsday presence is simply a rumor at this time and we probably won’t get confirmation of the Batman vs. Superman villain for a while.  Moreover, Mulvey is only one of the actors being considered for the role, so there’s no guarantee he’ll land the part.  Variety’s report also reiterates that there will be plenty of Justice League cameos in the film, with the Flash “a lock” to appear in some capacity.  We’ll find out for sure when Batman vs. Superman opens in theaters on July 17, 2015.
