On November 3, 2016, Rupert Gregson-Williams was hired to write and compose the film's music. He was joined by Evan Jolly, Tom Howe, Paul Mounsey, and Andrew Kawczynski, who provided additional music. The soundtrack was released on CD, digital, and vinyl the same day as the film. Australian musician Sia sang a song for the film, titled "To Be Human", featuring English musician Labrinth. Written by Florence Welch and Rick Nowels, the track is also featured on the soundtrack. The soundtrack also features samples from Wonder Woman's theme "Is She with You" from the Batman v Superman: Dawn of Justice soundtrack composed by Hans Zimmer and Junkie XL.
In the Silver Age, Wonder Woman's history received several changes. Her earlier origin, which had significant ties to World War II, was changed and her powers were shown to be the product of the gods' blessings, corresponding to her epithet, "beautiful as Aphrodite, wise as Athena, stronger than Hercules, and swifter than Hermes". The concepts of Wonder Girl and Wonder Tot were also introduced during this period.
In Wonder Woman Vol. 1 #204, Diana's powers and costume were returned to her and she is once again reinstated as Wonder Woman. I-Ching is killed by a crazy sniper in the same issue. Later, Diana meets her sister Nubia, who is Hippolyta's daughter fashioned out of dark clay (hence Nubia's dark complexion). Nubia claimed to be the "Wonder Woman of The Floating Island", and she challenges Diana to a duel which ends in a draw. Returning to her home, Nubia would have further adventures involving Diana.
The success of the superhero television series Supergirl informed the marketing and promotion strategy used for Wonder Woman. According to Time Warner chief marketing officer Kristen O'Hara, they wanted to approach the Wonder Woman marketing campaign in a light manner, similar to how they did with Supergirl. O'Hara elaborated that the modest campaign route they took for Supergirl aided in establishing a large central fanbase among women well in advance of the series, which reportedly generated 5 million female superhero fans in one week. They were then able to model over time, and grow that audience leading up to the 15-months-later release of Wonder Woman. Though neither the film nor the series are aimed exclusively at women, the latter's campaign gave them their first opportunity to begin collecting data about female superhero fans. In May 2017, a promo for Wonder Woman was released during the season finale of Supergirl, featuring a remix of the song "These Boots Are Made for Walkin'" and Supergirl (Melissa Benoist) wearing Wonder Woman's boots. The promo included an appearance by Lynda Carter, star of the 1970s Wonder Woman, who plays the American president on Supergirl.
The events of Crisis on Infinite Earths greatly changed and altered the history of the DC Universe. Wonder Woman's history and origin were considerably revamped by the event. Wonder Woman was now an emissary and ambassador from Themyscira (the new name for Paradise Island) to Patriarch's World, charged with the mission of bringing peace to the outside world. Various deities and concepts from Greek mythology were blended and incorporated into Wonder Woman's stories and origin. Diana was formed out of clay of the shores of Themyscira by Hippolyta, who wished for a child; the clay figure was then brought to life by the Greek deities. The Gods then blessed and granted her unique powers and abilities – beauty from Aphrodite, strength from Demeter, wisdom from Athena, speed and flight from Hermes, Eyes of the Hunter and unity with beasts from Artemis and sisterhood with fire and the ability to discern the truth from Hestia. Due to the reboot, Diana's operating methods were made distinctive from Superman and Batman's with her willingness to use deadly force when she judges it necessary. In addition, her previous history and her marriage to Steve Trevor were erased. Trevor was introduced as a man much older than Diana who would later on marry Etta Candy. Instead, Perez created Julia and Vanessa Kapatelis, a Greek-American scholar and her teenage daughter whom Diana would live with when she was in Man's world and would be major supporting characters in the series for years.
Elise Jost of Moviepilot observed that "Gadot's take on Wonder Woman is one of those unique cases of an actor merging with their story, similar to Robert Downey Jr.'s Tony Stark. Gal Gadot is Wonder Woman, and Wonder Woman is Gal Gadot." Jost praised Gadot's interpretation of Wonder Woman as the one in which Gadot "absolutely nails the character's unwaveringly positive outlook on life. She's a force of nature who believes in the greater good; her conviction that she's meant to save the world is stronger than her bullet-deflecting shield. She's genuine, she's fun, she's the warm source of energy at the heart of the movie." The Federalist suggests that Wonder Woman is "a story of Jesus". "The movie is wrapped up in faux Greek mythology, true, but there's no mistaking the Christology here." "Perhaps Christ in the form of a beautiful and kick-ass Amazon is all that our contemporary society can handle right now", stated M. Hudson, a Christian feminist. On HuffPost cultural critic, G. Roger Denson, who regards the superhero genre as a source of contemporary "Mainstream Mythopoetics" ("the making of new yet vitally meaningful, if not symbolic, stories filled with imagery reflecting, yet also shaping and advancing, the political, legal, moral and social practices of today"), wrote that the "No Man's Land" scene "that people are crying over in theaters and raving about afterward happens to be among the most powerfully mythopoetic scenes ever filmed at the same time it is one of the oldest myths to have been utilized by artists and writers after it had been invented by early military strategists and leaders." Specifically "used by director Patty Jenkins", the scene raises "the esteem for powerful yet compassionate women as heroes and leaders to a level equal with that of men for having won over a huge and adoring popular audience around the world".
The origin of Wonder Woman and the psychological reasoning behind why William Morton Marston created her in the way he did illustrated Marston's educational, ethical, and moral values. "William Marston intended her to be a feminist character, showing young boys the illimitable possibilities of a woman who could be considered just as strong as the famed Superman." Gladys L. Knight explains the impact and influences that superheroes have on us in society ranging from the 1870s until the present day.
