The datapad that Obi-Wan uses to track the ship signal to Daiyu is of the same design he had in Star Wars: Revenge of the Sith, where it was held by Anakin Skywalker in Padmé Amidala’s apartment.

Temuera Morrison’s cameo as a veteran of the 501st Clone Battalion shows not only a decade of neglect and despair, but also continued growth acceleration encoded into the clone’s biology. This genetic manipulation makes him appear far older than his 20 or so chronological years would suggest.

Though Temuera Morrison played clone troopers in Star Wars: Attack of the Clones and Star Wars: Revenge of the Sith, this is actually his first scene wearing clone armor. In the prequels, all clone bodies were computer generated; Morrison's face was superimposed in post-production.

The sabacc card that Haja hands to Obi-Wan is actually secretly marked: it features numbers that correspond with coordinates that would send to him to a location on Mapuzo.

One of the bounty hunters pursuing Kenobi on Daiyu looks similar to 4-LOM, but is in fact a different droid named 1-JAC. Though they're the same model droid, they sport differences in detail and weapons.
