It looks like X marks the spot for the Fast and Furious gang. 

In a new Instagram post, franchise star, Vin Diesel, revealed the title for the first installment in the two-part farewell to Dom Toretto's original crew: Fast X.

The reveal comes on the film's first day of production, with returning director Justin Lin behind the camera once again.

Funnily enough, Fast X has two fewer X's than Diesel's other action franchise, the XXX series, in which he plays extreme sports enthusiast/international adventurer Xander Cage.

The title also echoes the 10th installment of another long-running series, 2001's Jason X, which took the Friday the 13th boogeyman into outer space ... a final frontier that the Fast crew visited in the ninth movie.

On Twitter, fans are drawing connections to other X-related fare (including a certain franchise about merry Marvel mutants) and bemoaning the punny titles that might have been.

Seeing the design of the X in the logo really makes me hope that somehow this is a crossover between the Fast Franchise and the X-Men. https://t.co/ETsfsRFw3d

FastX sounds like ant killer you buy at Menards. Try again Mr Diesel.

Besides Diesel and all the returning racers, Fast X will introduce Jason Momoa and Brie Larson into the Fast-verse.

But the star's plans for a reunion with the Rock have hit a hard place. Dwayne Johnson has made it clear that he's not returning for one last ride as Luke Hobbs in a mainline F&F movie.

A Hobbs & Shaw sequel, on the other hand, is still on the table. Maybe that one can be called Hobbs & Shaw's Most X-cellent Adventure?
