Revenge of the Sith, in particular, removes all perceived jabs at the George W. Nearly all politics in the prequels were removed.The battle droids were all redubbed by Matthew Wood to sound like their The Clone Wars counterparts.Any CGI added in the original trilogy was also expunged and either replaced with the original shots or new shots. Almost all CGI in the prequels was replaced with various elements such as models, pyrotechnics, stop-motion, "go-motion", live-actors, matte paintings, and physical sets (the use of CGI was restricted to elements such as the lightsabers, lasers, shadows, and saber flashes, as well as digitally replacing actors' faces with those of deceased actors, and Yoda in the prequels' action sequences).The Battle of Endor was instead expanded with new shots.

Notable staff members who worked on the films include Adrian "Adywan" Sayce (best known for creating the Revisited fan edits of the Original Trilogy) who was appointed as the Ultimate Editions' producer and thus incorporated many of the edits he either created or proposed for Revisited he was also given full approval from Lucasfilm to continue his Revisited edits independently, as well as Petr Harmacek (creator of the Star Wars Despecialized Editions), who worked as a compositor on the edits, as well as the project supervisor (in collaboration with the group Team Negative1) for the restoration of the unaltered theatrical versions of the Original Trilogy. Production on the Ultimate Editions began on July 29, 2015, alongside Ultimate Editions of Indiana Jones and the Kingdom of the Crystal Skull and Howard the Duck. Current Lucasfilm CEO Dave Filoni and Star Wars creator George Lucas were brought into the project to serve as consultants. Johnson, a keen fan of Star Wars, stated in a 2014 interview that the Ultimate Editions were born out of his dissatisfaction with the Prequel Trilogy and many of the changes that had been made to the Original Trilogy, and wanted to make a completely new set that would cover almost everything that came from the franchise, as well as package the films with the original versions, all Special Editions of the films, and the so-called "Lost Cut" for A New Hope.
