Even though Wonder Woman 1984 isn't dropping until June of 2020, it still doesn't seem too early to wonder about a possible third installment.
In an interview with Vanity Fair, director Patty Jenkins revealed that she already has a third Wonder Woman movie worked out.
"I have pretty clear plans for Wonder Woman 3," Jenkins said. "Whether I [direct] it or not, I see how her arc should end in my incarnation of Wonder Woman. I have great passion for that."
The topic came up when Jenkins was asked about her dream projects, which included a New York love story in addition to this third Wonder Woman movie. With that in mind, it's worth noting that DC hasn't greenlit anything. And, furthermore, the state of the DCEU remains somewhat in flux, with rumors going back and forth about the involvement of both Henry Cavill and Ben Affleck in future projects as Superman and Batman, respectively.
Prior to James Wan's Aquaman, which has already made more than a billion dollars at the box office, Wonder Woman was the only franchise that did well with both critics and audiences. (To be fair, Suicide Squad is the one with the Academy Award.)
Anyway, even though Jenkins clearly has plans for a third film, there's no guarantee that it'll come to fruition. Although if Wonder Woman 1984 does well — and there's no reason to think that it won't, especially with star Gal Gadot returning in the titular role — the probability of Jenkins getting to close out the trilogy goes up significantly.
It also begs the question: What decade would Jenkins set the third Wonder Woman movie in? Hopefully, we'll be able to find out soon.
