Brie Larson plays who in Fast X?

Brie Larson plays who in Fast X? ...

Dominic Toretto's family has just gotten a bit bigger. With a cast list that's as impressive as any stunt ever seen on film, Fast X is shaping up to be one of the (if not the) most high-octane installments in the Fast franchise.

Vin Diesel, Michelle Rodriguez, Rita Moreno, Tyrese Gibson, Jason Momoa, Charlize Theron, Alan Ritchson, Scott Eastwood, Daniela Melchior, Dwayne 'The Rock' Johnson, Kurt Russell, Helen Mirren, Chris 'Ludacris' Bridges, oh, and Brie Larson are some of the most well-known names on the starting line.

Yes, the Marvel star is lending her talents to the Fast and The Furious universe, and we couldn't be more ecstatic.

Brie Larson is playing Tess, a mysterious character from Fast X, and while little is known about her role in the whole plot, speculation has been rampant.

Vin Diesel announced a "timeless" new twist to the storyline on Instagram, and we have our theories. Some have begun to suspect that Larson will play none other than Tess O'Conner, as in Brian O'Conner, Paul Walker's iconic role.

Tess isn't the type of person who wants to be messed with. Whether she'll be with the family, against the family, or somewhere in between is undefined. This is Brie Larson we're talking about, hero or villain, but we'll love her all the same.

Jason Momoa has been cast as the main antagonist in this film. A departure for the DC mainstay, he wants to introduce the world to his perspective on villainy in Fast X.

“It's been a while since I was the good guy,” says the narrator. He's a wacky person who's been a bit of a peacock...He's got a lot of troubles, this guy. He's definitely got some daddy issues.”

We can't help but appreciate the longevity of a franchise that can't help but entertain. May 19. Better get here fast.
