To find the perfect location to shoot the Amazon island of Themyscira, the birthplace of Wonder Woman herself, the film's producers searched all over the world, finally settling on the Cilentan Coast: a stretch of coastline on the Tyrrhenian Sea, located in the Province of Salerno in Southern Italy. It was chosen because most beaches in the world that sit below big cliffs disappear beneath the tide for part of every day. Production designer Aline Bonetto and her location manager Charles Somers considered 47 countries and visited several of them before they found what they were looking for. Bonetto explained that, "Italy had beautiful weather, a beautiful blue-green sea, not too much tide, not too much wave. Our effects team added some cliffs in post-production, and it was the perfect way to go". The estuary at Lower Halstow in Kent is featured in the scene in which Diana arrives at a Belgian creek to make her way to the warfront. Bill Westenhofer served as the visual effects supervisor for the film and Martin Walsh served as editor.
The girl who wondered has seen wonders... has become a woman who has traveled the world, who has traveled worlds! A woman who has touched countless lives, has made them better in ways beyond measure. A woman who has brought hope, and joy, and love. A woman who is the hero of so many. The truth of you has never changed, Diana. Even the gods themselves could not take that from you. Why would we? It's one of the many reasons we love you.
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.
This superhero era led by Kanigher didn’t last long though. The character was mired in the story lines from the golden age and especially her attachment to Steve Trevor. At the same time across the DC lineup characters were being revitalized with a new focus on science fiction. The silver age at DC is often attributed to having been started by the appearance of the re-imagined Flash in Showcase #4 in 1956. This led to a number of DC characters being reinvented such as Green Lantern and Hawkman. The difference with Wonder Woman though is that the character had managed to stay continually published since the golden age and did not get a science fiction retelling in the 1950s and 1960s. This left the character somewhat stilled mired in the past and eventually it was decided that something would be done to break her free of it. When the decision was made though it was decided that she would not have a science fiction background as it would break too much from her background as an Amazon, but that she would be slightly re-imagined as a martial arts based character, more along the lines of Batman. This would allow her to keep her somewhat unique background story, while also being more contemporary and popular. A much stronger emphasis was also placed on her appearance, as her somewhat drab civilian clothes and costume from the golden era were replaced with contemporary fashions of the time. In addition she opened a fashion boutique in trendy Greenwhich Village. This has led some to describe this era of the character as the “Mod Girl Wonder Woman.” While this version of the character did not prove to be consistently popular over the course of her brief run, it did leave some lasting impact on the character once she returned to her usual appearance. Following this she sought out more ambitious careers, for instance as a translator for the United Nations, or as a NASA astronaut and eventually moved back to Army Intelligence where she eventually got promoted to major. Also this period provided the opportunity to sever her from a dependence on Steve Trevor for her stories and her stories for the first time in her publication history became much more in line with what is considered typical of the super hero medium. The introduction of the multiverse made it such that there became two Wonder Womans, the modern version on Earth 1, and the golden age version on Earth 2. For a short time her appearances in her own comic were those of Earth 2 until the contemporary Angle Man accidentally visited her and subsequently the series was returned to modern day. The stories continued much like this for the remainder of the silver age until the end of the first Wonder Woman series with the events of Crisis on Infinite Earths. To provide closure to the character which was destined for a reboot, Steve Trevor returned and following the defense of Paradise Island from Shadow Demons, the two were finally married, though in continuity this lasted less than an issue.
Comic books were more or less invented in 1933 by Maxwell Charles Gaines, a former elementary school principal who went on to found All-American Comics. Superman first bounded over tall buildings in 1938. Batman began lurking in the shadows in 1939. Kids read them by the piles. But at a time when war was ravaging Europe, comic books celebrated violence, even sexual violence. In 1940, the Chicago Daily News called comics a “national disgrace.” “Ten million copies of these sex-horror serials are sold every month,” wrote the newspaper’s literary editor, calling for parents and teachers to ban the comics, “unless we want a coming generation even more ferocious than the present one.”
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.
