Patty Jenkins's 2017 big-screen version of Wonder Woman, starring Gal Gadot, was a massive commercial and critical hit. So it was hardly surprising when Warner Bros. announced that they were greenlighting a sequel shortly after the original film's release. But now sources close to the second installment in the franchise are saying that Wonder Woman 1984 won't be a sequel at all.

The upcoming film will feature Wonder Woman in a completely new adventure, which is partly why Jenkins chose to title it Wonder Woman 1984 as opposed to Wonder Woman 2, according to producer Charles Roven.

"[Jenkins] was just determined that this movie should be the next iteration of Wonder Woman but not a sequel,” Roven told Vulture. “And she’s definitely delivering on that. It’s a completely different time frame and you’ll get a sense of what Diana/Wonder Woman had been doing in the intervening years. But it’s a completely different story that we’re telling. Even though it’ll have a lot of the same emotional things, a lot of humor, a lot of brave action. [It] tugs at the heart strings as well.”

Though Jenkins has not confirmed this herself, a source close to the director told Vulture that Wonder Woman 1984 is indeed a standalone film. “It’s a standalone film in the same way that Indiana Jones or Bond films are, instead of one continuous story that requires many installments,” the source said.

Fans have already taken to social media to argue the semantics of what constitutes a "sequel," and they'll have a while to continue that conversation. Wonder Woman 1984 is set for a June 5, 2020 theatrical release.
