“It’s so exhausting to spend so much time nit-picking within your own head every detail of what you’re going to say,” she mentioned. “I needed to know that it was OK for me to do something that was silly or simple and it wouldn’t blow everything up, which sounds really absurd almost a year later.”
She handled vlogging like finding out for a brand new undertaking. “When I’m prepping for a role, it’s like getting a crush,” she mentioned. “You want to think about them, you want to talk about them, and everywhere you go, it’s almost like you get magical signs because your whole world is this love.”
Part of her analysis concerned video calling profitable YouTubers to be taught their secrets and techniques. In that first announcement video, there are moments the place Ms. Larson matches every vlogger’s emotional temperature.
“People love living vicariously through YouTubers, they love it, it’s weird,” Kelly Stamps, a vlogger, says in the video. “Like if you just go through my comments, people are just saying, ‘I love just seeing you be yourself on camera.’ Be relatable by just being honest.”
On a Zoom name in April, Ms. Larson tied up her damp hair and glued the collar of her tartan Batsheva smock gown. She had simply emerged from the sauna and ice bathtub, recovering from a coaching session for “Captain Marvel 2.” Sometimes, she vlogs her exercises together with her coach, Jason Walsh. “I just wanted to feel like in the human realm I could accomplish what she was doing in this superhero realm,” she mentioned. “And it helped me inform the character. It didn’t make sense to just stand there and be like, ‘The C.G.I. will take care of this.’”
Over the years, Ms. Larson has realized how “plastic” her thoughts and physique might be. “They can change for good and bad depending on what it is I’m doing,” she mentioned. She has struggled mentally by taking part in characters like Joy Newsome in “Room” and Grace Howard in “Short Term 12,” however with Captain Marvel and Kit from “Unicorn Store,” her directorial debut, she felt herself embracing some character traits and taking them house together with her.
