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.
Additional music featured in the film are: "Another Little Drink Wouldn't Do Us Any Harm" by Clifford Grey and Nat Ayer and performed by Edgar Trevor and Cecil Cooper; "Molly O'Morgan" written by Fred Godfrey and Will Letters and performed by Ella Retford; "It's a Long Way to Tipperary" written by Jack Judge and Harry Williams; "Sous les ponts de Paris" written by Jean Rodor and Vincent Scotto and performed by Lucienne Delyle; "I'll Walk Beside You" written by Edward Lockton and Alan Murray and performed by Ewen Bremner; "Green Grow the Rushes, O" written by Robert Burns and performed by Ewen Bremner; and "Schatzwalzer Op. 4" written by Johann Strauss II and performed by the Berlin String Quartet.
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.
