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.
Fans of modern day comic book characters would have some difficulty relating to characters from the early golden age, and Wonder Woman is no exception. In her first appearance in the comics, she has obviously fulfilled the role of an icon for readers, but so too did her secret identity, Diana Prince. The character was created in a time when different cultural and societal norms existed in North America.
The Pre-Crisis version of the invisible plane was a necessity because before Crisis on Infinite Earths rewrote Wonder Woman's history – along with the histories of many other heroes – Wonder Woman could not fly. She grew increasingly powerful during and after the Silver Age of Comic Books, acquiring the power to ride wind currents and imitate flight over short distances. This had limitations, however; for example, if there was no wind and the air was completely still she would be trapped on the ground or if dropped from a distance that she would helplessly fall out of control to the ground. Though this meant that she would rely on the invisible plane less frequently, she always had need of it.
The British War Council quickly gathered to discuss the notebook. Their codebreakers were unable to decipher the two different languages that it was written in, but Diana quickly identified them as Ottoman and Sumerian. She read the book out loud, informing the council that Doctor Poison had created a new form of mustard gas based on hydrogen instead of sulfur, which gas masks would be useless against.
Wonder Woman was created by the American psychologist and writer William Moulton Marston (pen name: Charles Moulton), and artist Harry G. Peter. Marston's wife, Elizabeth, and their life partner, Olive Byrne, are credited as being his inspiration for the character's appearance. Marston's comics featured his ideas on DISC theory, and the character drew a great deal of inspiration from early feminists, and especially from birth control pioneer Margaret Sanger; in particular, her piece "Woman and the New Race".
In 1954, Dr. Fredric Wertham alleged that there were lesbian subtexts to Wonder Woman and claimed comics contributed to juvenile delinquency in his book Seduction of the Innocent where despite a very obvious heterosexual relationship with Steve Trevor, Wertham asserted that Wonder Woman’s association with the Holliday Girls could be interpreted as a lesbian relationship. The Comics Code Authority was then introduced in reaction to Wertham 's claims against the entire industry.
