Fast X: First Look at Brie Larson, could she be playing Brian's sister?

 

Vin Diesel recently took to his Instagram, posting an image of himself and Brie Larson during filming of "Fast X", the tenth instalment of Universal's fats-moving franchise which reunites it's core cast members with some new players. Michelle Rodriguez, Jordana Brewster, Tyrese Gibson, Ludacris, Nathalie Emmanuel, Sung Kang, Scott Eastwood and Charlize Theron are all returning while newcomers Larson, Jason Momoa, Daniela Melchoir and Alan Ritchson round out the new cast. 

The upcoming sequel recently hit a snag when it's director Justin Lin, who directed the third, fourth, fifth, sixth and ninth movies exited the project a week into filming over "creative differences", later to be replaced by "The Incredible Hulk" director Louis Letterier. The script is from Lin and Dan Mazeau and is the first of a two-part closer for the franchise's main narrative story. Character and plot details are being kept under wraps, while it has been confirmed that Momoa is the film's villain alongside Theron's Cipher, Larson's character remains a mystery.

In his Instagram post, which suggests that there is family link, Diesel wrote the following "There are some people you will meet in life.... That will change you, change your family... change the world, FOREVER!", which also suggests that Larson is more than a random newcomer.

It has been speculated that Larson's new character is the sister to Brian O'Conner, who was played by the late Paul Walker in six of the "Fast" movies. No such character has appeared or been hinted in the movies, but it's entirely possible that could be the case. Walker died in a car accident in 2013 and the franchise has worked to keep his memory alive ever since. Walker's character was not killed-off but retired after 2015's "Furious 7", but the character's presence still exists in the franchise after that. His brother Cody Walker helped stand in for him to finish "Furious 7". However it's unclear if he'll be involved in the upcoming tenth instalment.
