Zack Snyder says Gal Gadot’s Wonder Woman plays a key role in Batman V Superman: Dawn of Justice

Batman V Superman: Dawn of Justice hits Cinemas in March and Director Zack Snyder has said that Wonder Woman isn’t just popping in as token fan service.
Gal Gadot’s Warrior Princess was included in the most recent trailer for Batman V Superman: Dawn of Justice to help the titular heroes leading many to believe that she has a glorified cameo in the film, but talking to Filmlink, Snyder promised that Wonder Woman serves a very important purpose revealing "It's bigger than a cameo. She comes in and does something.
It's an amazing opportunity to have Wonder Woman in the film. We haven't had a female superhero of that magnitude, and it's an amazing opportunity for the world to get behind an amazing, powerful female character.
I'm happy that we have the opportunity to do that. Half of my movies have female leads…maybe that's because I have so many strong women in my life.
I'm not in the least surprised by a strong female superhero. I'm shocked that it hasn't happened sooner."
Explaining why Gadot seemed a perfect fit for Wonder Woman, Snyder added "We tested a bunch of actresses, as you can imagine. But the thing with Gal is that she's strong, she's beautiful, and she's a kind person, which is interesting, but fierce at the same time.
It's that combination of being fierce but kind at the same time that we were looking for. She can get serious, but she's amazingly fun to be around. And by the way, she really held her own with Ben in the screen test. Ben was like, 'Whoa, that girl is something else!
That was a good sign, because Ben is very tough in the scene, and he's big and commanding. Anytime that you're doing a test like that and you're looking at the other person, you're thinking, 'OK, that's good stuff'.
That was part of the process, and over time as we got to know Gal, we found out how amazing she is."
Batman V Superman: Dawn of Justice hits Cinemas on March 25 and stars Ben Affleck, Henry Cavill, Gal Gadot, Diane Lane, Amy Adams, Holly Hunter, Jason Momoa, Jeffrey Dean Morgan, Jena Malone, Jeremy Irons, Jesse Eisenberg, Laurence Fishburne, Michael Shannon and Scoot McNairy.
