Although Brie Larson will debut as Carol Danvers in the Captain Marvel movie, that won't be the actress' first time working on a Marvel Cinematic Universe movie. It's finally been confirmed that Captain Marvel will appear in Avengers 4, which follows a few months after Carol's origin story. As with almost everything else in Avengers 4, we have yet to learn any specific details about Carol's involvement in that tale, but according to Black Widow herself, Scarlett Johansson, Larson had a particularly amusing moment on set which required her to get extremely close to costar Mark Ruffalo for a scene involving The Hulk. As Johansson described it:
We have Brie Larson on this film. She's here before shooting the stand-alone Captain Marvel movie so we get to watch her get her feet wet for real. She's so great, but a really cute thing happened the other day where Hulk is standing next to her and Joe Russo told her to put her hand in front of Mark [Ruffalo]'s face to stop him, and she's like, 'In front of his face?' And they explained, 'that's where his chest is,' and she looks up and yells, 'I'm new! I'm new!" I'm like, "damn, girl.'
Brie Larson already has some blockbuster experience under her belt thanks to Kong: Skull Island, but participating in a Marvel movie is a different kind of challenge. Not only is the MCU one of the more fantastical fictional words with its assortment of colorful superheroes and super villains, but Larson is jumping into a franchise where many of the main actors have been playing their respective characters for years already. (Infinity War will mark the 10th anniversary of Robert Downey Jr's debut as Iron Man!). So we don't blame Larson for having a little trouble imagining where her hand needs to line up to look like it's touching Hulk's chest. As for Mark Ruffalo, he's a pro at playing the Marvel game, so having someone's hand up in his face is par for the course nowadays.
After being an important member of the Marvel superhero community for nearly five decades, Carol Danvers is now only a few years away from making her theatrical debut. Following in the footsteps of Captain America: The First Avenger, Captain Marvel will be a period piece, with Carol obtaining her special abilities in the 1990s. Given that Avengers 4 take place in modern times, i.e. two decades later, it will be interesting to see how Carol is drawn into those events, not to mention how she'll still look the same. But having now read Scarlett Johansson's comments to Vanity Fair, it sounds like Carol will share some quality time with The Hulk. Maybe someone should teach her that lullaby to calm the Green Goliath down in case he's feeling particularly moody.
Avengers 4 will be released on May 3, 2019, but you can see Brie Larson's first Carol Danvers appearance before that when Captain Marvel opens on March 8 of the same year.
