Brie Larson is now an official part of Vin Diesel’sFast Xfamily, and a new photograph of the two actors offers a first look at what could potentially be her character in the film. The film is slowly turning out to be one of the most star-studded ones in the franchise, with several newcomers being added to the cast roster.

In April, Diesel had announced that Larson would be joining theFast Xcast and welcomed her to the family in an endearing social media post. He teased, at the time, that she would play a character thatFast and Furiousfansmay “not have expected but yearned for.” Details of her role have not been confirmed since, but it seems like she would be one of the good guys and a part of Dominic Toretto’s team. The latest image further teases the fact that she would be playing an integral role in the upcoming tenth installment.

The image in question features Diesel and Larson, and what could potentially be the first look at the latter’sFast Xcharacter. The caption reads, “There are some people you will meet in life… That will change you, change your family… change the world, FOREVER!” The image and words have started a whole new fan theory that Larson could potentially be playing a character that could be linked to a former member of the franchise. Fans believe that she could potentially be the sister ofPaul Walker’s Brian O’Connor.

Walker tragically died in a car accident during the filming ofFurious 7, and the film was completed with the help of his brothers and CGI. He received the perfect send-off in the franchise, with the final scene of the seventh installment showing him driving off into the sunset and reuniting with his family, with “See You Again” by Wiz Khalifa and Charlie Puth playing in the background. O’Connor might be gone, but fans are convinced that Larson is his long-lost sister who hasreturned to join Dom’s crew inFast X. Only time will tell how true this fan theory is.

Apart from Larson, Jason Momoa has also come on board as the villain inFast Xand Alan Ritchson is the latest one to join the roster in an unannounced role. However, while filming continues, the much-awaitedFast Xhas already suffered its share of problems, with long-timedirector Justin Lin stepping awayfrom the project. Unconfirmed reports suggest that Lin left the franchise due to issues with Diesel on set. This isn’t the first time that someone has left the franchise, as actor Dwayne Jonhson has vowed to never return to theFast and Furiousfranchise over differences with Diesel.

Fast Xis scheduled to premiere in theaters on June 19, 2025.
