In May 2017, early tracking had Wonder Woman opening with $65–75 million, and possibly as high as $105 million. The film opened Friday, June 2, 2017, across 4,165 theaters and made $38.7 million on its opening day, including $3.7 million in IMAX. It was the biggest single-day gross for a woman-directed film, ahead of the $35.9 million opening Friday of Catherine Hardwicke's Twilight in 2008 and the biggest opening day for a woman-led comic book superhero film, ahead of Ghost in the Shell ($7 million). This included $11 million it made from Thursday previews, also the best start for a film directed by a woman, surpassing Fifty Shades of Grey's $8.6 million which was directed by Sam Taylor-Johnson, and the third-biggest of the year, behind Beauty and the Beast and Guardians of the Galaxy Vol. 2. Of that, $1.5 million came from IMAX screenings.
Perhaps due to her Amazonian background, Diana greatly respects other noble selfless warriors, as evidenced when she attended Superman's funeral in Smallville and spoke of how he had been much more than a soldier (adding to what Batman said about Metropolis burying an empty casket). As a result of her great posthumous respect, she was, therefore, more than willing to aid Batman in honoring the heroic death of Superman, by helping round up the metahumans from Lex Luthor's files to form a team of superheroes (later known as the Justice League) to protect the world from the imminent mysterious alien invader Steppenwolf and his Parademon minions after Superman's death left the world vulnerable.
In the Golden Age, Wonder Woman adhered to an Amazon code of helping any in need, even misogynistic people, and never accepting a reward for saving someone; while conversely, the modern version of the character has been shown to perform lethal and fatal actions when left with no other alternative, exemplified in the killing of Maxwell Lord in order to save Superman's life.
The sister of Hippolyta, general of the Amazonian army, Diana's aunt and mentor. On being cast for the film, Wright said, "It's two-fold because when Patty Jenkins called me, the director, it was a three-minute long conversation. She said, 'I'm doing a movie about Wonder Woman. Do you want to be her trainer?' And I was like, 'Yes. Of course.' And the general of the Amazonian army. That was pretty cool." Describing her character mentoring and training Diana to be a warrior, Wright said, "It's a sixth sense that it is coming and I think that's also in the mythological story behind Antiope and Queen Hippolyta. They know it's coming and it's her duty as the aunt to her young niece to make sure she is the fiercest warrior of all time." On the Amazons fighting style, Wright said, "It's hand combat. Yes, swords and knives and arrows, but the precision that they have, right, as these warrior women; it's so nice to see that disparity between what we had in the day of just raw fighting materials and the guns and how easy that is in comparison." The message of the film, Wright stated, "is not just female empowerment. It's about love and justice. That's what the film's about. And what a great message to spread to our little ones." Commenting about training for the film, Wright said, "The most empowering was to get into that physical shape. So we were doing horseback riding training, weight training, martial arts, and 2,000 to 3,000 calories a day".
The Diana Prince alias also played an important role after the events of Infinite Crisis. Wonder Woman was broadcast worldwide killing a villain named Maxwell Lord, as he was mind controlling Superman into killing Batman. When Wonder Woman caught him in her lasso, demanding to know how to stop Superman, Maxwell revealed that the only way to stop him was to kill Lord, so as a last resort Diana snapped his neck. To recover from the trauma of killing another person, the Amazon went into a self-imposed exile for one year. On her return to public life, Diana realized that her life as a full-time celebrity superhero and ambassador had kept her removed from humanity. Because of this she assumed the persona of Diana Prince and became an agent at the Department of Metahuman Affairs. During a later battle with the witch Circe, a spell was placed on Diana leaving her powerless when not in the guise of Wonder Woman.
