A story emerged not long after Wonder Woman came out that director Patty Jenkins had to fight to keep the No Man's Land scene in the movie. It turns out that people weren't trying to cut the scene or anything like that, as Jenkins told Richard Donner (via Cinema Blend) in an interview:

"It's funny, I feel badly about this cause it's been reported that Warner Bros. was against it, which it was not Warner Bros., it was my own people in England. It was our own crew at points, who were like, 'Why are you doing this scene? She's not even fighting anything,' So Warner Bros. was not unsupportive of the No Man's Land scene. It was much more in-process that everybody was like, 'What's this scene for? There's no one to fight. We've already seen her block a bullet in the alley and then she's going to go in and save this church tower, why do you need this other scene?'"

Jenkins went on to realize that this is because Diana isn't directly fighting someone. She's blocking bullets and walking across No Man's Land.

"It's funny, because it makes you realize superheroes fight other people. And this was really just a scene about her. And so it was an interesting thing. I kept saying, it's about her—it's not about anybody else. It's only about her. Then, it was fine. The people who were questioning it, I said, 'Don't worry about it.' Just let me do it."

So it was more that the people on the ground didn't understand the context of what Jenkins was trying to do — not that Warner Bros. didn't want the scene in the movie.

Summary: Before she was Wonder Woman she was Diana, princess of the Amazons, trained warrior. When a pilot crashes and tells of conflict in the outside world, she leaves home to fight a war to end all wars, discovering her full powers and true destiny.

Wonder Woman, directed by Patty Jenkins, stars Gal Gadot, Chris Pine, David Thewlis, Robin Wright, and Connie Nielsen. It's available on VOD today and on Blu-ray on September 19th.
