Diana's uniform as Wonder Woman, designed by Queen Hippolyta, features emblems of America, the land to which she will be returning Steve Trevor. A golden belt will be the source of her strength and power while away from Paradise Island. She has her bullet-deflecting bracelets and also receives a golden lasso which is unbreakable and forces people to obey and tell the truth when bound with it. As shown later in flashback, Hippolyta also teaches Diana how to transform her clothes magically into the uniform.
The modern age of the character can be tied to the reboot of the character following Crisis on Infinite Earths. In this the character became defined by the vision of George Perez in a way which the entire concept of the character was defined by his direction. As opposed to the past where the character would get retold origins which would try to make her more contemporary, now she got one which tied her much more strongly to the stories of the ancient gods. For the first time Diana enters Man’s World not knowing how to speak English already, and is forced to master the language on her own. In this period she also became much more closely related with modern female issues, and this was usually through her circle of friends – Julia and Vanessa Kapatelis and Mindi Mayer. Such issues as the cultural need for women to be attractive and thin, suicide and the sensationalization of the media as it pertains to women were all addressed. This version of the character also reimagined Steve Trevor as a father figure for Diana as opposed to a romantic counterpart. After Perez’s run on the character, she was taken over for a time by William Messner Loebs, who recast her again in somewhat more traditional superhero stories, though in this case she still explored a different aspect of humanity. After a long space voyage, when she returned home she was forced to work at a fast food restaurant to pay her bills and made friends with a number of people in her “civilian identity.” This built up to the revelation of betrayal of her mother, and of Artemis taking over as Wonder Woman for a short time, but this was soon reversed. The following writer was John Byrne, who when he was writing Superman in the post-Crisis on Infinite Earths DC universe, had hinted at a relationship between Diana and Superman. This was explored occasionally under his run, but it is probably best known for the death of Diana, and the assumption of her duties by Hippolyta. She was soon returned to life (as she had never really died, instead having been deified). This period also introduced Cassandra Sandsmark, who would go on to become Wonder Girl at a later point. The remainder of this second series is best remembered for by the writing of Jimenez and Rucka, both of whom helped define the character. The latter during the lead-in of events to Infinite Crisis had Diana fighting Superman who was being controlled by Maxwell Lord. Battered after their battle, Diana has managed to stop Superman by using her lasso of truth on Lord, and the only option which she is given to stopping him is to kill him, and realizing this is the case, she does so. This created a controversy both within comics and in the real world, as both fans and characters alike debated the morality of this decision. In comics this also led to strained relations between her and Superman and her and Batman and with the addition of the events of Identity Crisis, helped to lead to the breakup of the Justice League of America at a crucial point right before the main events of Infinite Crisis were about to begin.
From September 5 to 11, filming occurred at the fortified complex The Alcazaba of Almería and the Wall of Jayran in Almeria.

Carolyn Cocca has stated that Wonder Woman possesses a "duality of character" due to the character possessing both feminine and masculine qualities in her physical abilities and attitude, which Cocca felt made her more appealing to a wide audience. Wonder Woman's first female editor, Karen Berger, claimed that, "Wonder Woman [is] a great role model to young women, but also contains many elements that appeal to males as well. Wonder Woman crosses the gender line.". Berger worked with George Pérez on the new issues of Wonder Woman starting in 1987, and the new Diana "works with friends and allies to teach lessons of peace and equality."
Vox stated "Trevor is the superhero girlfriend comic book movies need". The San Francisco Chronicle's Mick LaSalle lauded the performances of Gadot, Pine, Huston, and Thewlis while commending the film's "different perspective" and humor. Richard Roeper of Chicago Sun-Times described Gadot's performance as inspirational, heroic, heartfelt and endearing and the most "real" Wonder Woman portrayal.
Filming occurred outside the U.S. Capitol in Washington D.C. during mid-June.
