According to Zack Snyder, Batman vs Superman's Wonder Woman is a 5000-year old former superhero coming out of retirement.
Remember when Warner Bros revealed Bruce Wayne was a superhero before the events of Batman v Superman: Dawn of Justice? Well, Batman's got nothing on Wonder Woman. According to director Zack Snyder, Gal Gadot's version of Diana is 5000 years old, and started her hero career long before its other characters were born. In fact, Batman v Superman is what draws her from retirement, kicking off events that lead into the upcoming Justice League film.
"It was incredibly organic how Wonder Woman came into the story," Zack Snyder told Empire magazine. "The whole concept came of, 'Let's not save anything. Let's try it all.' Then Wonder Woman's entrance made us realize we were much closer to the Justice League than we thought. We realized we were one movie away.
Snyder is referencing Wonder Woman's comic book origins as both an unaging Amazonian princess and one of the most powerful warriors of the DC Universe. It's a fairly bold move, considering past attempts to adapt Wonder Woman weren't so faithful or far reaching. Presumably this Wonder Woman has fought supervillains well before the events of her World War I-era film, opening all kinds of doors into DC Universe history.
We don't know what caused Dawn of Justice's Wonder Woman to retire from crime-fighting, but Gal Gadot herself offered some hints. "She's seen it all, she has seen what humans can do, so it was very hard for her to come back," Gadot explained, adding that Diana Prince behaves a little differently 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."
We already knew Wonder Woman would have a superheroic past, but making that history several millenia long was unexpected. And that's just the latest Batman v Superman plot reveal, following news that Jesse Eisenberg is playing Lex Luthor's son and Doomsday has a role to play in Justice League. It's certainly going to make for a complicated DC cinematic universe when Dawn of Justice launches on March 25, 2016.
