New First Order Speeder Bikes, based on previously released Hasbro and Lego toys, can be spotted in the hangar that Tam, Yeager, Kaz and CB escape into.
During the final battle, Bucket is flying the Fireball without a human (co-)pilot.
The Mouse Droid that Tam Ryvora re-purposes is called 5-L. The production team named him after Fievel from An American Tail (1986).
In the first draft of the script, Tam was to send her secret message in Neeku's native language, "Kada'sa'Niktoese." This was changed to a secret mechanic's code the two of them came up with to make it more personal and private.
In early stages of story development, Kaz, Tam, and Yeager's plan would have involved attempting to sabotage the Star Destroyer's Hyperdrive. However, this ended up resembling a mission in Star Wars: Battlefront II (2017). So it was decided they would send out a warning message to the Colossus instead.
