Development for a live action Wonder Woman feature film began in 1996, with Ivan Reitman attached as producer and possible director. In 1999 the project became attached to Jon Cohen, who adapted Wonder Woman for producer Joel Silver, with the hope that Sandra Bullock would star. By 2001, Todd Alcott was hired to write the screenplay, with Silver Pictures backing the project. At that time, performers such as Mariah Carey and Catherine Zeta-Jones were also rumored to be possible candidates for the role of Wonder Woman. Leonard Goldberg focused on Bullock who said that she was approached for the role. Lucy Lawless, the star of Xena: Warrior Princess, was also under consideration, though she stated that she would have been more interested if Wonder Woman was portrayed as a "flawed hero". The screenplay went through various drafts written by Alcott, Cohen, Becky Johnston, and Philip Levens, and by August 2003, Levens had been replaced by screenwriter Laeta Kalogridis.
During the Silver Age, under writer Robert Kanigher, Wonder Woman's origin was revamped, along with other characters'. The new origin story increased the character's Hellenic and mythological roots: receiving the blessing of each deity in her crib, Diana is destined to become as "beautiful as Aphrodite, wise as Athena, strong as Hercules, and swift as Hermes."
The story behind the writing and editing of Wonder Woman can be pieced together from Bender’s papers, at Brooklyn College; Frank’s papers, at the University of Minnesota; and Marston’s editorial correspondence, along with a set of original scripts, housed at the Dibner Library at the Smithsonian Institution Libraries. In his original scripts, Marston described scenes of bondage in careful, intimate detail with utmost precision. For a story about Mars, the God of War, Marston gave Peter elaborate instructions for the panel in which Wonder Woman is taken prisoner:
Their first adventure together as a serious couple involved a battle with Doomsday, a monster of Kryptonian legend. Superman, already familiar to the monster, explained that Doomsday was sealed into a pocket dimension called the Phantom Zone. Seeking preparation against enemies that could match them in power, Wonder Woman asked Hephaestus to forge weapons for them. Later, the Justice League intercepted the arrival of General Zod, another Kryptonian survivor. Superman gave him shelter in the Fortress of Solitude, but the couple discovered their relationship was now public knowledge.
Their greatest champion, Princess Diana soon lost her life against the demon Neron. Hera (now presiding over Olympus) transfigured Diana into a goddess of truth and welcomed her to live with the gods. Diana was told she could not interfere with the daily lives of mortals, unless prayed to. Hera sits on the throne. The gods shared the secret of their division with Diana and decided to reunite their essences with those of their Roman counterparts. Diana could not be prevented from interfering with the mortal world and so she was banished to Earth. She was soon also stripped of her immortality.
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.
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.
