Dwayne Johnson said he tried hard to get Jason Momoa to play the role of Hobbs's brother, but scheduling issues prevented it from happening. However, Johnson gave fans hope for a future collaboration, adding, "Next Hobbs movie for sure." Vin Diesel then proceeded to go against Dwayne's plans by casting Momoa in Fast X as the sadistic, androgynous and flamboyant son of Fast Five's main villain, Hernan Reyes.

When the attack on Samoa begins, it is supposed to be right before dawn. However, by the end of the attack it is midday. Since there was a 30 minute timer set right before the battle starts and just finishing up when the battle ends, it is clear that only 30 minutes passed. It should still be just after dawn when the action completes.

2 mid-credits scenes with Ryan Reynolds, and one post-credits scene with Hobbs getting his own back on Shaw, for his airport stop 'n' search.

The ending is slightly different, depending on where you watch it. On TubiTV, for example, the climax is followed by a denouement consisting of Hobbs with Shaw arguing the various merits of sidekicks; shots of a cityscape; Queenie in jail and visited by Shaw and Hattie, who give her a suspicious birthday cake; Hobbs going home and introducing Sam to her grandmother. This is followed by a short scene with Champ calling Hobbs, warning him about a second virus, then more credits, then Hobbs calling Shaw, whom has been snitched out to the police, then the remainder of the credits. Finally, we return to the Hobbs and Champ phone call, and the film ends. In a version shown in Russia, however, after Champ has warned Hobbs about the second virus and the credits restart, the rest of Champ's call is shown on a side-by-side with the credits, followed by the remaining credits, and finally the Hobbs call to Shaw, ending the film. In summary, the order of the calls with Champ and Shaw have been reversed.
