Brie Larson is ready for her close-up. She's joining the superhero universe as one of the more prominent female superheroes in the comic book world. "Captain Marvel" is part of the next phase of the Marvel Cinematic Universe. On Thursday (Jan. 25), fans received a first peek as to what the character would look like ahead of her cinematic debut. And they were pretty pleased with the results. Well, some anyway. Not everyone is going to be satisfied, but everyone is going to get a sneak peek of the character.

Larson dons the costume

Page Six was among the first outlets to release pictures from the "Captain Marvel" set on Thursday.

Fans of the character quickly noticed an issue, though. In the comic books, the character has a very defined suit, with a recognizable color palette. She is well known to wear red, blue, and gold. Those were not the colors Larson was wearing on her suit, though. Instead, she was donning a suit that appeared to be teal and green.

Fans took to Twitter with different theories. Some believed the suit was more of a prototype, in the way many characters in the MCU adjust their costume as necessary. Others think the movie might be set in a different time, opening up the possibility of a different costuming choice.

Knowing the MCU, there probably won't be answers until the first trailer for the movie drops. Until then, all we have to work off of is Brie Larson in a Captain Marvel suit.

More on 'Captain Marvel'

Very little is known about "Captain Marvel" at the moment. The film was announced way back in October 2014. In July 2016, Larson was cast as Carol Danvers, the real name behind the superhero.

A few months later, Anna Boden and Ryan Fleck signed on to direct the film. It will be their first feature film since 2015's "Mississippi Grind," although they have directed some television shows in the interim, including "Billions" and "The Affair."

Basically, the only known fact about the plot is that the movie is going to be set in the 1990s (which might explain part of Larson's unusual costume).

There's also a release date a little more than a year away: March 8, 2019. Larson will reprise "Captain Marvel" less than two months later in the Avengers film, set to be released on May 3, 2019.

Larson is best known for winning an Academy Award for Best Actress with her performance in "Room." She's about to become synonymous with the Marvel Cinematic Universe, though, for better or worse.
