Earlier this year, the DC Extended Universe made a bombshell revelation when it confirmed that Joss Whedon was being brought in to take on a Batgirl movie. The unexpected news left fans gawking as Warner Bros. has already made announcements with DC Entertainment about a new film focusing on Nightwing. However, it looks like the Bat Family can’t be contained.

Since the announcement was made, Whedon has kept mostly to himself about the project, but a few rumors have circulated here and there. Mostly, fans have been busy fan-casting the role of Barbara Gordon, and many have started to wonder if Whedon has an actress in mind for the role. However, when it comes down to it, the director says he’s still in the process of nailing the character down. Earlier tonight, Whedon spoke with Variety on the red carpet for Guardians of the Galaxy Vol. 2, and he was asked about Batgirl.

“There’s so many things to say about her. I’m very excited to see a girl in the cowl,” he started. But, when it came time to talk casting, Whedon stressed he did not have any actresses in mind yet. “No, I don’t have my eye on anybody. I’m creating this character. I’m in a dialogue with her. We’ll see who joins that later on.”

Continuing, Whedon said. “I think this is somewhere where you go and find Batgirl and then you cast her.” When the director was asked whether he wanted a fresh-face for the role, Whedon said he was not necessarily opposed to bringing in big name talent. “I’m not against movie stars. They’re great, but you need somebody who’s going to be just right. And, in a situation like this, the name carries a lot of weight,” he said before dropping a final zinger. “[It’s] definitely Vin Diesel.”

In Justice League, fueled by his restored faith in humanity and inspired by Superman’s selfless act, Bruce Wayne enlists the help of his newfound ally, Diana Prince, to face an even greater enemy. Together, Batman and Wonder Woman work quickly to find and recruit a team of metahumans to stand against this newly awakened threat. But despite the formation of this unprecedented league of heroes—Batman, Wonder Woman, Aquaman, Cyborg and The Flash—it may already be too late to save the planet from an assault of catastrophic proportions.
