The call sign of the Stormtrooper TK8252 who appears in the end cut-scene of the second level "Asteroid Crust" in the game's expansion pack Star Wars: Jedi Knight: Mysteries of the Sith, is the LucasArts' phone extension number of the game's lead level designer, Kevin Schmitt. Ryan Kaufman, one of the game's designers who named the character, would later recite TK8252's dialogue from the scene whenever he had to remember the phone extension.
The game's cutscenes featured the first new lightsaber footage filmed in 14 years, since the release of Return of the Jedi in 1983.
In "Level 5: Baron's Hed - The Fallen City", early in the level a woman can be seen entering and leaving from a nearby building. If the player is quick enough, they can get past her and enter inside where they'll find Max, from the Sam & Max series, standing on a chair armed with a blaster. If they interact with him, he'll accompany the player and fire at enemies. However if the player decides to shoot at Max, he'll start attacking you.
