Marvel Studios closed out an elaborate Hall H presentation Saturday night by officially confirming that Oscar winner Brie Larson would be the first actress to headline one of their massively successful superhero movie in 2018’s Captain Marvel. The 6,000-plus audience erupted into thunderous applause and the reception online was also largely enthusiastic. There were a few die-hard Captain Marvel comic-book fans who weren’t entirely sold on the idea but, according to comic writer Kelly Sue DeConnick, Larson deserves the gig.

DeConnick—who now writes the enormously popular comic Bitch Planet—didn’t create the character of Carol Danvers, who has been kicking around the Marvel comics universe (mostly as “Ms. Marvel”) since 1968. Nor was it her idea in the early 2010s to give Carol the promotion from Ms. to Captain. But working as a Marvel freelancer, DeConnick wrote Carol’s Captain Marvel debut from 2012 to 2015 and, though she won’t take full credit, is widely considered the reason for the character’s massive popularity. So the die-hard, vocal Danvers fans (whom DeConnick nicknamed “the Carol Corps” during her run) were eager to see what their unofficial leader would say about the Larson news. But last night on Twitter—barring a few tacitly supportive retweets—the usually vocal DeConnick kept quiet. The fact that she was just getting back home to Portland from her own whirlwind weekend at Comic-Con might have something to do with that. But don’t mistake her silence for disapproval.

“I was very careful about not wanting to cheer for anyone in particular,” DeConnick said of the line she’s been walking ever since the Captain Marvel movie was announced in 2014. Speaking with Vanity Fair over the phone Sunday morning, DeConnick added, “I’m in a position where so many of the fans will look to me for a cue. I didn’t want anyone who was cast to feel unsupported or second choice.”

Did DeConnick have a different actress in mind for the role? She did, but you’d need a time machine to pull it off. “My dream casting—or the actor who is the voice in my head—is Kathleen Turner from about 1983. She could be both sexy and awkward and powerful. She could do all of those things at once. From what I can tell, Brie Larson can do those things too. She has a gravitas and she has a power to her. But you can see she also has a sense of humor and playfulness there. I’m psyched.”
