Wonder Woman's character was created during World War II; the character in the story was initially depicted fighting Axis military forces as well as an assortment of colorful supervillains, although over time her stories came to place greater emphasis on characters, deities, and monsters from Greek mythology. Many stories depicted Wonder Woman rescuing herself from bondage, which defeated the "damsels in distress" trope that was common in comics during the 1940s. In the decades since her debut, Wonder Woman has gained a cast of enemies bent on eliminating the Amazon, including classic villains such as Ares, Cheetah, Doctor Poison, Circe, Doctor Psycho, and Giganta, along with more recent adversaries such as Veronica Cale and the First Born. Wonder Woman has also regularly appeared in comic books featuring the superhero teams Justice Society (from 1941) and Justice League (from 1960).
Gloria Steinem, editor for Ms. magazine and a major supporter of Wonder Woman, stated "... [Marston] had invented Wonder Woman as a heroine for little girls, and also as a conscious alternative to the violence of comic books for boys." Badower described a near-international incident (involving an unnamed Russian general rolling dozens of tanks and munitions through a shady mountain pass) as an outstanding example for standing up to bullies. "She ends up deflecting a bullet back and disarming the general," he says, adding that "she doesn't actually do anything violent in the story. I just think that Wonder Woman is smarter than that."
A day before Whedon's departure from Wonder Woman, Warner Bros. and Silver Pictures purchased a spec script for the film written by Matthew Jennison and Brent Strickland. Set during World War II, the script impressed executives at Silver Pictures. However, Silver stated that he had purchased the script because he did not want the rights reverting; while stating the script had good ideas, Silver did not want the film to be a period piece. By April 2008, Silver hired Jennison and Strickland to write a new script set in contemporary times that would not depict Wonder Woman's origin, but explore Paradise Island's history.
The costs for television advertisements for Wonder Woman are higher in comparison to that of previous DCEU film Suicide Squad. Warner Bros. has spent over $3 million on advertisements for Wonder Woman, whereas they spent $2.6 million on advertisements for Suicide Squad. Ticket selling site Fandango reported that Wonder Woman rounded the final leg of its marketing campaign as the most anticipated blockbuster of summer 2017, according to a poll conducted by 10,000 voters, the biggest survey in company history. Separately, Fandango also found that 92% of people surveyed said that they are looking forward to seeing a film that features a standalone woman superhero, and 87% wished Hollywood would make more women-led superhero films. In May 2017, NASCAR driver Danica Patrick drove her No. 10 car with a Wonder Woman paint scheme at the Go Bowling 400 in Kansas and at the Monster Energy Open in Charlotte.
Impressed by this unknown woman's self-sacrifice, the Amazons entombed her with honors and clothed her in armor displaying the American flag pattern on her uniform, which they assumed were her heraldic colors. Trevor's legacy was also the primary reason why Ares arranged for Steve Trevor to bomb the island, as he could not resist the irony of the heroine's son unwittingly killing her admirers.
