Captain Marvel is finally confirmed for Untitled Avengers as Brie Larson joins the cast for filming in Atlanta. It has been over a year since Larson joined the Marvel Cinematic Universe in a role that will make her the first female hero to lead a film on her own in this universe. However, in the time since her casting, details on her have remained scarce. Marvel Studios gave audiences some details on her solo film this summer by revealing a young Nick Fury would join the 1990's set Kree/Skrull war.

With there being plenty of reasons to be excited for Captain Marvel, many fans are already looking forward to how she'll interact with the rest of the universe. Marvel's been hesitant to confirm if or where Carol Danvers would appear outside of the solo film, but we now know that she'll definitely be in Avengers 4.

Photographer account Atlanta Filming has revealed that Brie Larson has reported to set today to begin work on the team-up flick. With her not expected to be in Avengers: Infinity War, this will be the first time she interacts with fellow heroes of the MCU. On her first day on set, it appears as though it will be a meeting of two Captains, with Chris Evans also said to be there filming. UPDATE: new photos posted by Just Jared further confirms this news:

Hi... #BrieLarson :) (And #ChrisEvans...) Like Chris is an after thought when Brie is here.— Atlanta Filming (@AtlantaFilming) September 18, 2017

Even though it is not a surprise that Brie Larson is appearing in Avengers 4, it is still great to get basically official word that she is in it and has now started filming. If this is indeed her first day on set, then it also marks Larson's first time actually playing Carol, which is probably equally exciting and nerve-racking for her. She is an Oscar-winner at the end of the day, but starring opposite Jacob Tremblay is not quite the same as standing next to Chris Evans and probably even more MCU stars.

Now that Larson is on set, it may not be long before fans get to see what she actually looks like in her costume. Set photos always come out from these major blockbusters, and even though Marvel unveiled concept art of her look at SDCC, it will be nothing compared to the first actual look of her suited up. Marvel's security is notoriously tight however and they may go to extra lengths to make sure her involvement will not leak. But, since she's already been spotted on set or reporting to it, getting a look at her in some way is not out of the question moving forward.
