Deep into production, Director Brian O'Connell and supervising director Dave Filoni had to start over almost from scratch thanks to new input from George Lucas. Lucas brought in footage from war movies including Battle of the Bulge (1965), The Longest Day (1962), Saving Private Ryan (1998) and Black Hawk Down (2001) to illustrate the kind of action he wanted them to incorporate into the second battle of Geonosis.
Clone Commander Jet is named after Jett Lucas, son of George. The Clone Wars Character Encyclopedia reveals his Clone number to be 'CC-1993', referring to Lucas's year of birth.
Dave Filoni intentionally chose to feature Jet instead of Bacara, aka CC-1138 (from Star Wars: Episode III - Revenge of the Sith (2005)) as Ki-Adi Mundi's clone commander. This is to show that not all clone troopers live to serve under the same Jedi Generals for the duration of the Clone Wars.
Ki-Adi-Mundi's gunship has a skull-faced clone trooper helmet painted on it, with the phrase "SEPARATIST NIGHTMARE" written on it in Aurebesh.
Western war movies always show the good guys move from left to right and the bad guys right to left during battle scenes, as Western audiences are used to reading from left to right. This story arc, like Star Wars: Episode II - Attack of the Clones (2002) before it, shows the Republic Forces moving from right to left instead. This foreshadows the Clone Army becoming the Imperial Army.
