(For the record, Marston and Olive Byrne’s son, Byrne Marston, who is an 83-year-old retired obstetrician, thinks that when Marston talked about the importance of submission, he meant it only metaphorically. “I never saw anything like that in our house,” he told me. “He didn’t tie the ladies up to the bedpost. He’d never have gotten away with it.”)
In late 2013, Zack Snyder cast Gal Gadot in the role of Wonder Woman for the 2016 film, Batman v Superman: Dawn of Justice over Élodie Yung and Olga Kurylenko. Some fans initially reacted to this choice by criticizing Gadot's appearance. Snyder would later comment on his decision to cast Gadot, stating that he 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. Gadot described Diana as having "the heart of a human so she can be emotional, she's curious, she's compassionate, she loves people. And then she has the powers of a goddess. She's all for good, she fights for good." She also said that Diana has "many strengths and powers, but at the end of the day she's a woman with a lot of emotional intelligence". As to how her character is different from her appearance in Batman v Superman: Dawn of Justice, Gadot said "We go back 100 years to when she's more naive", further explaining, "She's this young idealist. She's pure. Very different to the experienced, super-confident, grown-up woman you've seen". Gadot underwent a diet and training regimen, practiced different martial arts and gained 17 pounds of muscle for the role. Gadot was previously offered a different role (as a villain) in Man of Steel, which she declined because she was pregnant at the time; this allowed her to later be cast as Wonder Woman in the film's follow-up. Gadot signed a three-picture deal. She was paid a base salary of $300,000 for the film itself.
As Diana, Victor and Arthur all try to simultaneously flank Superman (albeit unsuccessfully), Barry attempts to help using his speed, but Superman is able to see him and keeps up with the speedster. Despite Barry's best efforts, Superman is able to land a glancing blow, knocking him out before Batman arrives and gets Superman to stop. Wonder Woman tries to fight Superman again, yet she's knocked down. He then swats Batman and asks him the same question that Bruce asked him "Tell me, do you bleed?". Before Superman could kill Bruce, Lois and Alfred to stop him.
Unfortunately, not long after Diana left, Hera came for her vengeance, and though she could not bring herself to kill Hippolyta, she could not forgive her either. Feeling regret at giving up the only real family she had, Wonder Woman returned to Themyscira to find the Amazons absent, and her mother turned to stone. Shortly after, Wonder Woman encountered Lennox, a man who claimed to be another of Zeus' bastard children. After learning that Zeus has gone missing, they confronted the Gods of Olympus, Poseidon and Hades, in order to prevent them from taking over Zeus’ throne. To prevent a war between gods, Diana proposed that the two brothers share Heaven with one ruling during the day, and the other at night. Hera angrily interceded, which was what Diana had planned, and using Hermes' staff she transported herself to Mount Olympus to face Hera alone. She warned that she would make Hera regret what she had done to her mother before returning to Earth. Unfortunately, by the time she had returned, Hades had kidnapped Zola with the warning that Diana would need to make good on her bargain or Zola and her child would die.
Seeking answers, Wonder Woman sought out an old friend that she believed could provide the way to Themyscira: Barbara Minerva, the Cheetah. Cheetah agreed to help, under the condition that Diana kill the plant-god Urzkartaga and free Barbara from her curse, which Diana agreed to do. When she located Urzkartaga, however, she discovered Steve Trevor and some of his fellow soldiers had been captured by Colonel Andres Cadulo, who intended to become the embodiment of the god and sacrifice Steve in the process. Wonder Woman freed dozens of Cadulo's captives and, with the help of Cheetah and the women he had captured, succeeded in destroying Urzkartaga and freeing Barbara from the curse of the Cheetah. With Barbara's help, Diana and Steve were able to find "Themyscira", though Diana was surprised to find her mother alive and well despite remembering her as dead at the hands of Hera. After removing her bracelets Diana realized that her past interactions with these representations of the Amazons and her home were in fact an illusion, and that she may have never returned home since she originally left to escort Steve to the United States. Upon this realization, Diana suffered a mental breakdown.
“I have the good Sergeant’s letter in which he expresses his enthusiasm over chains for women—so what?” As a practicing clinical psychologist, he said, he was unimpressed. “Some day I’ll make you a list of all the items about women that different people have been known to get passionate over—women’s hair, boots, belts, silk worn by women, gloves, stockings, garters, panties, bare backs,” he promised. “You can’t have a real woman character in any form of fiction without touching off a great many readers’ erotic fancies. Which is swell, I say.”
Despite their displeasure at Diana's capture, Hephaestus was able to bring Lennox and Eros to Hades with him as guests to the wedding, without the aid of Hermes' staff. As the wedding drew nearer, Hades grew annoyed that few of his relatives had agreed to come. Diana's friends were the only attendees, aside from Strife, who merely wanted to cause her namesake emotion. Before the wedding ceremony took place, Hades insisted that Diana should prove her love by wearing his ring. The ring was a noose fashioned with the Lasso of Truth, and if Diana did not truly love him, he would kill her.
The next day, Diana awoke to find that they'd hitched a ride on a larger ship and arrived in London. She was less than pleased at the sight of the city, stating that it was hideous. As they walked through the streets of London, Diana insisted that Trevor take her to the war. She was dismayed to hear that he intended to deliver Doctor Poison's notebook to his superiors in the British War Council. Trevor promised that if he went with her to deliver the notebook, he would take her to the war. Though annoyed by the detour, Diana agreed. Trevor then realized that she was only wearing her battle armor, and took her to a store to buy her some clothes. As they walked to the store, Diana was delighted to see a baby and ran toward it, with Trevor having to pull her away.
Coming to America for the first time, Wonder Woman comes upon a wailing army nurse. Inquiring about her state, she finds that the nurse wanted to leave for South America with her fiancé but was unable due to shortage of money. As both of them looked identical and Wonder Woman needed a job and a valid identity to look after Steve (who was admitted in the same army hospital), she gives her the money she had earned earlier to help her go to her fiancé in exchange for her credentials. The nurse reveals her name as Diana Prince, and thus, Wonder Woman's secret identity was created, and she began working as a nurse in the army.
