Wonder Woman
Carter's acting career took off when she landed the starring role on Wonder Woman in 1975, as the title character and her secret identity, Diana Prince. The savings she had set aside from her days of touring on the road with her band to pursue acting in Los Angeles were almost exhausted. Carter has publicly stated that, on the day she got the part, she had $25 in the bank. She was close to returning to Arizona when her manager informed her that Joanna Cassidy had lost the role and Carter had the part of Wonder Woman. Carter's earnest performance greatly endeared her to both fans and critics. As a result, she continues to be closely identified with Wonder Woman.
The Wonder Woman series lasted for three seasons, from 1975 to 1979. It first aired on ABC, and later on CBS. Carter's performance, rooted in the character's inherent goodness combined with a comic-accurate costume and a catchy theme song, made for a depiction that was considered iconic. After the show ended, Carter told Us that "I never meant to be a sexual object for anyone but my husband. I never thought a picture of my body would be tacked up in men's bathrooms. I hate men looking at me and thinking what they think. And I know what they think. They write and tell me." The 2018 journal article "Casting a Wider Lasso: An Analysis of the Cultural Dismissal of Wonder Woman Through Her 1975-1979 Television Series" argued that the show strongly adapted Wonder Woman's ideals but "was suppressed, undone, and discredited" by American culture as part of a larger legacy suppressing the character.
In 2017, Carter explained her perspective of portraying the Diana Prince/Wonder Woman character. Carter says she got the role back in 1975 largely because she looked the part, which was both a blessing and—as one of the show's producers warned her—a curse, saying that "Oh, women are going to be so jealous of you." Carter had responded, "Not a chance. They won't be, because I am not playing her that way. I want women to want to be me, or be my best friend!". As Carter describes portraying Wonder Woman, "There is something about the character where in your creative mind for that time in your life where you pretended to be her, or whatever the situation was, that it felt like you could fly".
In 1985, DC Comics named Carter one of the honorees, in the company's 50th anniversary publication Fifty Who Made DC Great, for her work on the Wonder Woman series.
In 2007, DC Direct released a 13-inch (330 mm) full-figure statue of Carter as Wonder Woman, limited to 5,000 pieces; it was re-released in 2010. Also in 2010, DC Direct began selling a 5+1⁄2 in (140 mm) bust of Carter's Wonder Woman to celebrate the 75th anniversary of DC Comics.
During production of the 2017 Wonder Woman feature film, director Patty Jenkins approached Carter to appear in a cameo role in the film, as Carter confirmed, "Patty asked me to do a cameo in this. She was in England, and I was doing my concerts," explaining she had singing engagements that made her unavailable. "At that time we couldn't get our timing together. So, this next time, if she writes me a decent part, I might do it." Carter did make a cameo in the post-credits scene of the sequel film, Wonder Woman 1984 where she plays Asteria, the "Golden Warrior" of the Amazons.
Carter holds dear the new film and the character introduced more than 75 years ago. "Many actresses or actors, they want to divorce themselves from a role because we are actors, we really aren't the people that we play. But I knew very early on that this character is much more than me certainly, and to try to divorce myself from the experiences that other people have of the character is silly," she said.
