The Citadel combat scenario seen during the clone training sessions in "Clone Cadets" are named after the Citadel installation in this trilogy.

The Expanded Universe of Star Wars novels originally had Even Piell survive the Clone Wars only to be killed while as a fugitive in the early days of the Empire. Piell's death in the Citadel Mission is the character's true fate.

When Saesee Tiin refers to "the Old Republic," he is talking about the government that predates the modern founding of the Galactic Republic 1,000 years ago. That is a time of great strife and conflict, when the Sith battled against the Jedi.

The Plo's Bros gunship that rescues the strike team from Lola Sayu is designated a "space gunship", with a sealed cabin and search spotlights mounted in the gunnery sockets.

The anoobas are actually a concept designed for Episode I by concept artist Terryl Whitlatch, who explored the sharp-toothed hound as a possible creature on Tatooine.
