John Ratzenberger returns to the role of Major Derlin for the first time since Star Wars: Episode V - The Empire Strikes Back (1980). However, in that film he was seen but not heard, as his lines were dubbed by another actor while in this case he is heard but not seen, as his part is represented by an animated Lego version of the character.
The Aurebesh text visible on Quarrie's datapad translates to "Proton Suspension" & "Priority high".
Kordi calls Hondo a "Sleemo", which is Huttese for "slimeball".
The opera that Derlin listens to inside the Escape Pod is "Squid Lake" from the opera house scene in Star Wars: Episode III - Revenge of the Sith (2005).
