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.
Apollo Wonder Woman #3 (February–March 1943) Apollo is the God of the Sun, Music, Poetry, Oracles, Healing, and Medicine, and the younger twin brother to Artemis who is based on the god of the same name. In the New 52, Apollo sought to claim the throne of Olympus after Zeus had gone missing. He was eventually killed by the First Born, though he has since returned.
The Invisible Plane was a creation of Diana's during her younger years on Paradise Island. She created it to be an improvement on her mother's planes which would be shot down in Man's World. The result of her innovation was an invisible plane that could fly at terrific speeds silently and not be detected by hostile forces. Initially, it was portrayed as being transparent.
A stand-alone #0 issue was released in September which explored Diana's childhood and her tutelage under Ares, the God of War, now known most often as simply 'War'. The issue was narrated in the style of a typical Silver Age comic book and saw Diana in her childhood years. The main plot of the issue was Diana training under War as he thought of her being an extraordinary girl with immense potential. The issue ultimately concluded with Diana learning and experiencing the importance of mercy, which she first learned when War showed it to her during their sparring. This later translated into her refusal to kill the Minotaur – a task given to her by War; however, this show of mercy makes her a failure in War's eyes, which was actually his fault since he inadvertently "taught" her mercy and affection as his protege. Later in the series, Wonder Woman is forced to kill War during a conflict with her evil half-brother, Zeus' son First Born, and herself becomes the God of War. After the Amazons are restored, she rules over them both as a warrior queen and God of War, as the ongoing conflict with First Born escalates. At the end of Azzarello's run, as part of a final conflict, Wonder Woman kills First Born, while Zeke is revealed to have been Zeus' plan for resurrection, with Zola revealed to have been a mortal shell for the goddess Athena, who gave birth to Zeus just as he once did to her. Wonder Woman pleads with Athena not to allow the Zola personality, whom she has grown to love as a friend, die with Athena's awakening. Athena leaves the site in animal form, leaving a stunned and confused Zola behind with Wonder Woman.
Steve Trevor's secretary who befriends Diana. Describing her character, Davis said, "She's a woman in a man's world and so being heard and seen aren't the easiest things, but it kind of doesn't deter her", adding, "Etta is unapologetically herself and I think that that's the thing that has drawn me to her the most". When asked if she was previously familiar with the character, Davis responded, "No. I wasn't. It took me a while to know that I was auditioning for Etta because even when I found out it was Wonder Woman, I still had no idea what the role was. It took a little while then I Googled the character". On Etta Candy's relationship with Steve Trevor, Davis said, "One of the great things that Etta gets to work with Steve Trevor is because Steve is not your typical man, in that he does entrust her with things that in 1918 probably wouldn't have been entrusted to a secretary of somebody who is quite important", further explaining, "So I think that [Trevor] needs her just as much as she needs that because now she's been given responsibility that she wouldn't have normally be given before, and equally he has somebody who could probably fly under the radar a bit. So he can trust the person who no one's really looking at".
Shortly after, Diana decides to venture to the Underworld to look for Zola. Lennox requests to come, but Diana shoots down his attempt, saying that she is going solo, save for Hermes as the only way to go to Hades is to either die or be escorted by Hermes. While in the Underworld, Hermes tells that the place is more or less an extension of Hades' (now preferring to call himself "Hell") will.
