The script originally called for black-hued retail droid guards to haul Master Ropal's unconscious body.

Long time fans will find something familiar in the term "Kyber memory crystal." In early drafts of the original script to A New Hope, the Kyber crystal was a Force-focusing artifact wanted by the Jedi and the Sith. This was eventually written out of the story in subsequent drafts, and a variation of the artifact -- spelled as the Kaiburr crystal -- made its way into the 1978 novel Splinter of the Mind's Eye. During the script development of Episode II, the term "Kyber" was nearly resurrected. The weapon that Jango Fett used to kill Zam Wesell was first identified as a Kamino kyber dart. This was changed to saber-dart in the finished movie.

Rex orders Execute Battalion to board "ATAT300," but the proper designation for the Clone Wars-era walker is an AT-TE. The other walker identified by number is 773.

When Anakin confronts the three doomed battle droids in the airlock corridor, the one in the background them panics and frantically tries to activate the controls.

Trooper Denal was last seen in the season one episode, "Downfall of a Droid."

A small but grim detail for sharp-eyed viewers. The dead body of Bolla Ropal has its tongue sticking out.
