Vin Diesel wants Robert Downey Jr. to portray the 'antithesis' of Dominic Toretto in this film.
Dwayne the Rock Johnson originally didn't want to return to the franchise due to his real life feud with Vin Diesel. Vin Diesel stated, "It was no easy task, because so much has been created in this universe." He also stated, "To tie up all these storylines, this character needed to come back into the mythology."
This would be the final movie of the franchise.
Would mark the third time actors Jason Momoa and Gal Gadot have worked together following Justice League (2017) and In The Hand Of Dante (2024). If Dwayne Johnson has a role in this movie it will also mark the fourth time him and Gal Gadot have worked together following Fast Five (2011), Fast and Furious 6 (2013) and Red Notice (2021).
The franchise may end in a 2 part finale instead of 3.
