Expert Social Intuit: Wonder Woman, as Diana Prince, has a high degree of social confidence (having had a century of experience living in "Man's World" after World War I), allowing her to intuitively determine how to interact with others, gain their respect and get her point across with calmness, eloquence, and charisma. Hence, Diana swiftly befriended the Wonder Men, she diplomatically greeted Bruce Wayne, matter-of-factly showing him that she can intellectually keep up with him (calmly responding to Bruce's anger at having been stolen from by her), she tactfully accepted a wine glass from the Gotham City Museum of Antiquities curator (despite seemingly disliking alcoholic beverages), she tactfully avoided correcting the curator on his claim that the fake replica of Alexander the Great's sword was the actual relic, and only when Lex Luthor insulted her father Zeus' memory did Diana have a look of visible dismay on her face (but even then she avoided making a scene), and only when Batman insulted her beloved Steve Trevor's memory did she finally lose her temper and shove Batman back. As a result, Diana remains extremely well-respected at the Louvre Museum, by fellow antique museum curators, by the Justice League, and even the extremely experienced Batman is almost instantly intrigued by her.
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.
On occasions Wonder Woman has employed a magical sword of unknown (though presumably Amazon) origin. This sword has been used most specifically against those with the power of invulnerability as invulnerability generally does not work against magical items. It is generally represented as a short sword. In Wonder Woman (vol. 4) #15, Hephaestus modifies Diana's bracelets so that she can manifest two short swords from them during battle.
Chris Pine was cast as Steve Trevor, a character he described as a "rogue-ish, cynical realist who's seen the awful brutish nature of modern civilization" and added that he is a "worldly guy, a charming guy". He signed a multi-picture deal. Lucy Davis' performance as Etta Candy is the first live-action cinematic portrayal of the character. As well, Elena Anaya's performance as Doctor Poison is the cinematic debut of that character. Nicole Kidman was in negotiations for the role of Queen Hippolyta, but was forced to drop out due to scheduling conflicts with Big Little Lies.
Wonder Woman and the other heroes were finally released from the Firestorm Matrix when Batman used the Lasso of Truth on Firestorm. Superman was still infected with the Kryptonite shard inside his nervous system, but Lex Luthor was able to extract it, saving Superman's life. Luthor also assembled a group of villains that defeated the Crime Syndicate. Later, at the Batcave, Wonder Woman and the Justice League talked about the enemy that destroyed the Crime Syndicate's world and came to the conclusion that Darkseid would return.
