Development of a live action Wonder Woman film began in 1996, with Ivan Reitman slated to produce and possibly direct. The project floundered in development hell for many years; Jon Cohen, Todd Alcott, and Joss Whedon, among others, were also attached to the project at various points. Warner Bros. announced the film in 2010 and Jenkins signed on to direct in 2015. Inspiration for Wonder Woman was drawn from Wonder Woman creator William Moulton Marston's 1940s stories and George Pérez's 1980s stories about Wonder Woman, as well as the New 52 incarnation of the character. Principal photography began on November 21, 2015, with filming taking place in the United Kingdom, France, and Italy before finishing on May 6, 2016, the 123rd anniversary of Marston's birth. Additional filming took place in November 2016.
This section of the history takes place during the New 52, between the events of Flashpoint and DC Rebirth. It was later revealed that much of Wonder Woman's history from this time was an elaborate illusion created by the Gods of Olympus to keep her away from Paradise Island. All or part of this section may have been part of that illusion and no longer valid in Rebirth.
The first of these half-mortal siblings to reveal himself to Wonder Woman was her older half-brother, Lennox Sandsmark, who could transform himself into living, marble-like stone and, before his death, was revealed to be the father of Wonder Girl (Cassie Sandsmark). His killer, the First Born, the eldest progeny of Zeus, would become Wonder Woman's first major super-villain of the New 52.
At the time of her debut, Wonder Woman sported a red top with a golden eagle emblem, a white belt, blue star-spangled culottes, and red and golden go-go boots. She originally wore a skirt; however according to Elizabeth Martson, "It was too hard to draw and would have been over her head most of the time." This outfit was entirely based on the American flag, because Wonder Woman was purely an American icon as she debuted during World War II. Later in 1942, Wonder Woman's outfit received a slight change – the culottes were converted entirely into skin-tight shorts and she wore sandals. While earlier most of her back was exposed, during the imposition of the Comics Code Authority in the mid-1950s, Wonder Woman's outfit was rectified to make her back substantially covered, in order to comply with the Authority's rule of minimum exposure. During Mike Sekowsky's run in the late 1960s, Diana surrendered her powers and started using her own skills to fight crime. She wore a series of jumpsuits as her attire; the most popular of these was a white one.
