The 34-year-old actress appeared to be enjoying her time at the event, during which she FaceTimed her costar, Samuel L. Jackson.
The performer, whose newest film has received polarized responses from critics, opted for an all-black outfit that included a leather jacket worn on top of a slim-fitting blouse.
Larson also donned a maxi skirt and a pair of knee-high boots while attending the event.
The Academy Award-winning performer’s bright blonde hair contrasted well with the dark tone of her clothing.
The actress reprised her longtime role as Carol Danvers, also known as Captain Marvel, in The Marvels, which was released in the United States on Friday.
She made her debut as the superheroine in 2019’s Captain Marvel, and she reprised her role in Avengers: Endgame, which was also released that year.
The Marvels was centered on the character, who teamed up with Monica Rambeau and Kamala Khan, played by Teyonah Parris and Iman Vellani, after the three began unexpectedly swapping places with one another.
The cast of the movie, which was directed by Nia DaCosta, was rounded out by performers such as Zawe Ashton, Park Seo-joon and Gary Lewis.
Jackson also reprised his longtime role as Nick Fury in the newly released feature.
Development on the feature officially began in 2020, and physical production on the project ran from 2021 until 2022, although reshoots took place earlier this year.
The Marvels debuted in Las Vegas this past Tuesday, although its stars were unable to attend the premiere event due to the now-concluded SAG-AFTRA strike.
The feature has since received mixed reviews from critics, and it currently holds a 62% rating on Rotten Tomatoes.
Larson spoke about portraying Captain Marvel during an interview with Harper’s Bazaar and admitted that she was initially afraid that taking on a high-profile role would keep her from pursuing her personal interests.
She recalled: ‘I was scared of what would happen to me. I was like, “What world is this, where these are the choices I have to make as an artist?”
The actress then stated that she stood behind her decision to portray the superheroine and remarked that she had attempted to separate her professional and personal lives over the past few years.
‘Anytime I feel like I’m being put too much on a pedestal, it’s my job to figure out how to remove that within myself,’ she said.
