Director Zack Snyder tells the newspaper that adding DC Comics characters such as Batman (Ben Affleck), Wonder Woman (Gal Gadot) and Cyborg (Ray Fisher) makes the movie "thicker, denser and more epic" than Man of Steel and allows it to be the next step toward building a strong movie universe that will ultimately lead to Snyder's Justice League.
USA Today adds that "'Dawn of Justice' continues to immerse Superman on Earth by working at the Daily Planet as Clark Kent along with Lois Lane (Amy Adams) and Perry White (Laurence Fishburne). But it also takes him to new environments such as Gotham City and introduces larger threats, including Lex Luthor (Jesse Eisenberg). The debuting heroes Superman meets will affect his perspective on Earth and on the ones he loves, and Snyder feels his convictions will be drawn into question as well."
As far as Affleck's Batman, Snyder said to expect an older, road-weary take on the Dark Knight. "It's cooler to see a crusty old Batman beating the snot out of guys," he said.
Snyder also explained the 'v' in the title instead of the traditional 'vs.' They did it "to keep it from being a straight 'versus' movie, even in the most subtle way."
Snyder added that he has yet to film any scenes with Gadot as the Amazonian princess. "She's working out and getting buff and ripped."
