The Diana Prince alias also played an important role after the events of Infinite Crisis. Wonder Woman was broadcast worldwide killing a villain named Maxwell Lord, as he was mind controlling Superman into killing Batman. When Wonder Woman caught him in her lasso, demanding to know how to stop Superman, Maxwell revealed that the only way to stop him was to kill Lord, so as a last resort Diana snapped his neck. To recover from the trauma of killing another person, the Amazon went into a self-imposed exile for one year. On her return to public life, Diana realized that her life as a full-time celebrity superhero and ambassador had kept her removed from humanity. Because of this she assumed the persona of Diana Prince and became an agent at the Department of Metahuman Affairs. During a later battle with the witch Circe, a spell was placed on Diana leaving her powerless when not in the guise of Wonder Woman.
During Marston's run, Diana Prince was the name of an army nurse whom Wonder Woman met. The nurse wanted to meet with her fiancé, who was transferred to South America, but was unable to arrange for money to do so. As Wonder Woman needed a secret identity to look after Steve (who was admitted to the same army hospital in which Diana Prince worked), and because both of them looked alike, Wonder Woman gave the nurse money to go to her fiancé in exchange for the nurse's credentials and took Diana Prince as her alias. She started to work as an army nurse and later as an Air Force secretary.

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.
