A year after Wonder Woman comics writer Greg Rucka acknowledged that his interpretation of the iconic heroine is "queer," fans are lobbying Warner Bros. to depict her big-screen counterpart as bisexual in the 2019 sequel.

A petition launched on Change.org by Gianna Collier-Pitts, a GLAAD campus ambassador at New York University, calls on the studio to "directly acknowledge Diana Prince for who she is, who she has always been (regardless of her current love interest), and what her character could potentially represent for millions of people."

More than 2,200 people have signed the petition since its launch on Thursday.

"Wonder Woman’s Diana Prince hails from Themyscira, land of the Amazons and inhabited exclusively by women," Collier-Pitts wrote. "This alone should serve as reason enough to confirm her sexuality, since any close relationship she could have had prior to her romantic storyline with Steve Trevor would have had to have been with another woman. Some of you may be thinking that this specificity doesn't make a difference but for people like me who rarely see themselves reflected in media, believe me. It does. [...] Making Wonder Woman canonically bisexual on the big screen would make her the first openly LGBTQ superhero of any gender from either DC or Marvel's cinematic universes, and would solidify her place as a true role model for women of all ages and identities."

Rucka noted in September 2016 that the sexuality of Wonder Woman, and the Amazons, is "complicated," explaining, "This is inherently the problem with Diana: We’ve had a long history of people — for a variety of reasons, including sometimes pure titillation, which I think is the worst reason — say, 'Ooo. Look. It’s the Amazons. They’re gay!' And when you start to think about giving the concept of Themyscira its due, the answer is, 'How can they not all be in same sex relationships?' Right? It makes no logical sense otherwise."

Wonder Woman star Gal Gadot addressed the issue shortly thereafter, acknowledging that, while it wasn't explored in the original film, "when you talk theoretically about all the women on Themyscira and how many years she was there, then what he said makes sense. In this movie she does not experience any bisexual relationships. But it’s not about that. She’s a woman who loves people for who they are. She can be bisexual. She loves people for their hearts.”

Directed by Patty Jenkins, Wonder Woman has grossed $819.5 million worldwide. The sequel, which will reteam Jenkins and Gadot, is in development for release on Dec. 13, 2019.
