New information on Wonder Woman’s character, when we first meet her in ‘Batman v Superman’:
“It was incredibly organic how Wonder Woman came into the story,” Zack Snyder tells Empire Magazine about the decision to include Wonder Woman in Batman v Superman: Dawn of Justice. “The whole concept came of, 'Let’s not save anything. Let’s try it all.’ Then Wonder Woman’s entrance made us realise we were much closer to the Justice League than we thought. We realised we were one movie away.”
[…] The magazine then goes on to reveal that this version of Wonder Woman is over 5000 years old when we first meet her, and that she’s put her superhero days behind her before unknown circumstances force the character to give up her retirement. Why though has she stopped protecting the world? “Because she’s seen it all, she has seen what humans can do, so it was very hard for her to come back and fight,” Gadot explains before weighing on what separates Diana Prince from Wonder Woman. “They have the same attitude. Although when she is Diana she tries to blend in, she is not too outgoing. I don’t want people to think she is perfect. She can be naughty.” (x)
