Normally I wouldn't link from ComicBook, but it comes straight from Kevin Feige.Black Panther: Wakanda Forever has added Dominique Thorne to its cast, the actress who will be playing Ironheart in the Marvel Cinematic Universe. Thorne had previously been announced as the MCU's Riri Williams for the hero's self-titled Ironheart series coming to Disney+. Marvel Studios president Kevin Feige has confirmed to ComicBook.com that Thorne will make her MCU debut as Ironheart ahead of the release of her self-titled series.
"We're shooting Black Panther: Wakanda Forever, right now, and the character of Riri Williams, you will meet in Black Panther 2 first," Feige said in an interview surrounding the release of Shang-Chi and the Legend of the Ten Rings. "She started shooting, I think, this week before her Ironheart series."
