Though we don't know many details about the movie, we do know it'll explore the dynamic between Parris's Monica and Larson's Carol Danvers that was teased in "WandaVision."
"Yes, when Monica was an 11-year-old girl, with her mom and Auntie Carol, they had a beautiful relationship," Parris told ComicBook.com in 2021. "And so I think what's been awesome with 'WandaVision' is getting to see Monica grow up, and we haven't seen her for 20 years plus, or however many, and getting to see slowly, it's being revealed what her life has been since we last saw her. And so Carol Danvers was a part of her life when we last saw her, and seeing that there is still, there is something there, I think is very exciting." Parris added that the "Captain Marvel" sequel "gives us space to further explore what might be happening" between the two characters.
"The Marvels" also picks up where the "Ms. Marvel" TV series ended, with all three women entangled and switching places.
