In 2010, Warner Bros. stated that a Wonder Woman film was in development, along with films based on DC Comics superheroes the Flash and Aquaman. Both Wonder Woman and Aquaman were still under consideration for solo film subjects as of June 2013. DC Entertainment president Diane Nelson said Wonder Woman "has been, since I started, one of the top three priorities for DC and for Warner Bros. We are still trying right now, but she's tricky." On October 5, 2013, WB chairman and CEO Kevin Tsujihara said he wanted to get Wonder Woman in a film or on TV. Shortly afterward, Paul Feig said he had pitched the studio an idea for Wonder Woman as an action-comedy film. The studio then began to search for female directors to direct the film. While Michelle MacLaren was the studio's initial choice to direct (and while she initially indicated interest), she eventually left the project due to creative differences.
With Artemis' help, Wonder Woman tracked Zola down to a subway station, where they found a lock of fox fur. Realizing that Zola was with Dionysus, they went to Providence, where Dionysus was currently located. They found Dionysus captured by Cassandra's minion, the Minotaur. When Cassandra's forces were about to depart to Olympus, Wonder Woman ambushed them and hung onto their plane. When the jet arrived to Olympus, the mountain was hit by a massive explosion.
A shocked Diana apologized to Antiope and abruptly left the training session. She wandered off to a cliff on the Themysciran seashore and examined her gauntlets in awe. As she stood there, she noticed an airplane burst through the forcefield surrounding Themyscira and crash in the nearby waters. Seeing even from a great distance away that someone was trapped inside the sinking aircraft, she leaped down the ocean and rescued the pilot, none other than a human soldier named Steve Trevor. She pulled him out of the water and onto the Themysciran shore. As he came to, she noted in disbelief that he was a man, as she had never seen one before. Though somewhat confused, Steve affirmed that he was, rhetorically asking whether or not he looked like one.
The chief chemist associated with General Ludendorff who specializes in chemistry and poisons. On her role, Anaya said, "Well, it was a small role in this big ensemble, but it is an important character in the story. I'm going to be a big nightmare" for Wonder Woman and Steve Trevor. Describing her character, Anaya said, "Dr. Maru loves rage and enjoys people's pain. She's creating terrible weapons, and her purpose in life is to kill as many people as possible, and provoke as much pain as possible". She researched World War I and Fritz Haber, the scientist who created mustard gas, to prepare for the role. On the character's facial scars, Anaya stated, "I went to Patty Jenkins and asked, 'What happened to her?' And she said, 'She did it on purpose.' I was like, 'What? Patty, you're going further than I ever imagined.' She said, 'She wants to provoke painful suffering, so she tested her own gas on her own face. She wanted to know how deep this form of her gas would go, so she put it on her own face.' You can see half of her face is completely gone. This is the sadistic side of Dr. Maru". She also stated her character "is quite the opposite to the lead role of this movie, one of the strongest characters ever of DC comics, Wonder Woman. I can tell you that Doctor Poison is someone with a capacity to provoke so much pain." On Dr. Maru's relationship with General Ludendorff, Anaya said, "I think that they have a relationship based on loyalty. Ludendorff is a very tormented General that lacks self-confidence. That's why, in part, he takes these drugs that Dr. Poison gives him. They are from different worlds, but they complement each other".
Wonder Woman's signature weapon was her Lasso of Truth; consequently, much of her crime-fighting powers came from bondage, and her only exploitable weakness was, essentially, bondage. Grant Morrison and Yanick Paquette had teamed up to work on Wonder Woman: Earth One. Paquette confirmed that he and Morrison would be bringing back the bondage theme that was popular in Wonder Woman comics during the 1940s. However, he stated that Morrison was looking for a way to not only modernize it, but to use the bondage theme as a form of female empowerment. Paquette acknowledged that Wonder Woman has become more than just a beloved character, she is a symbol for feminism. "By bringing in sex and, yes, bondage, it reasserts [William Moulton Marston's core] idea that it is okay for women to have a healthy sexual appetite." Paquette elaborated more on this by pointing out the blatant double standards in comics when it comes to sex: "Could Wonder Woman really ever have a healthy and active sex life without it becoming political fodder for Fox News? And what of women and girls who want to be like her? Do we truly think they wouldn't be labeled sluts? I have my doubts."
When last we left Wonder Woman #49, the battle brewing ever since DC's METAL cracked open the Multiverse seemed to be reaching its climax. With the Dark Gods playing similar roles to the Greek pantheon, but with all-powerful demands, enslaving humanity, Diana and her twin brother Jason were splitting up to oppose them around the globe. Just as they seemed to knock back their leader, King Best, the Dark Gods launch an assault on Jason.
