The Amazon Queen of Themyscira and Diana's mother. After meeting the director for the role, Nielsen said, "Patty and I met in London, and we just hit it off from the get-go. We couldn't stop talking. What was supposed to be a one-hour meeting turned into a two-and-a-half-hour lunch and we just really got each other." She described Jenkins's directing style for the film as "She's also the kind of director that I really flourish under. She has very strong and particular and specific ideas about what it is she wants to say. She comes from a place of strength always. And so, when you are dealing with someone like that, you feel absolutely free to be vulnerable, to be creative, and I am a big researcher." On playing the character, Nielsen said, "It was a complete and utter pleasure and I absolutely loved every second of playing her." On her character being Diana's mother and Amazonian queen, Nielsen stated, "I'm queen and I'm preparing my child for a world that entails a lot of responsibility. So it was important to me to bring that into the character." She read The Amazons by Adrienne Mayor to familiarize herself with women warriors and said "I used what I learned in Mayor's book as a rallying cry for how I approached Hippolyta. And then, of course, what is a leader who is elected by her peers every year and has been doing this for a thousand years? That too was interesting to think about". Nielsen went through a workout regimen for the film, saying "I did six hours a day. You know, two hours of weight training, two hours of swords training, and then two hours of horseback riding".
Wonder Woman is suggested as being queer or bisexual, as she and another Amazon, Io, had reciprocal feelings for each other. Grant Morrison's 2016 comic Wonder Woman: Earth One, which exists parallel to the current DC comics Rebirth canon, Diana is depicted being kissed on her right cheek by a blonde woman who has put her left arm around Diana.
“As to the ‘advanced femininity,’ what are the activities in comic books which women ‘indulge in on an equal footing with men’? They do not work. They are not homemakers. They do not bring up a family. Mother-love is entirely absent. Even when Wonder Woman adopts a girl there are Lesbian overtones,” he said. At the Senate hearings, Bender testified, too. If anything in American popular culture was bad for girls, she said, it wasn’t Wonder Woman; it was Walt Disney. “The mothers are always killed or sent to the insane asylums in Walt Disney movies,” she said. This argument fell on deaf ears.
