Ben Affleck has explained how Wonder Woman impacts his character in Batman v Superman: Dawn of Justice.

Affleck told EW that the third member of the DC comic trinity is important to his character's development, especially given his cynicism after years of fighting crime. Spoilers follow.

Affleck said that the Batman of this continuity is world-weary and has grown cynical, and even bitter from the loss of a Robin. All this fuels his suspicion towards Superman, providing the major conflict, but Wonder Woman has been fighting injustice for much longer and hasn't grown jaded.

"It inspires in him the idea that well, if there’s one of these kinds of people out there, then maybe there are in fact more," he said. "If there are more, then maybe that’s hopeful and also terrifying to him, because then they could make humans even more powerless — or they could serve on our side. You’ve got to remember that Batman is the world’s greatest detective, and if he suspects that there may be more, and if he suspects in particular that Diana may be somebody special, he gets inspired."

Of course, Batman historically is very suspicious of his superhuman colleagues in the comic books, even coming up with contingency plans in case they go rogue. He also has a history of romance with Wonder Woman in the comics.

Batman's suspicion is largely because Superman nearly leveled a city in a super-brawl during Man of Steel. Superman actor Henry Cavill had some of his own thoughts on that subject recently in another interview. Batman v Superman: Dawn of Justice opens March 25.
