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.

Early on in Level 5 "Barons Hed: The Fallen City", if you scare the villagers in Barons Hed, they will run away, and you can follow one fleeing woman who will open the locked door of a house near a bridge. If you can get inside the house fast enough, Max from Sam & Max, a franchise whose first game Sam & Max Hit the Road was developed and published by LucasArts, can be found inside sitting in a chair wielding a modified Bryar pistol (which is ironic since the Bryar pistol is already a modified Bryar rifle) that shoots highly-damaging green bolts instead of red. Max also has a high amount of health similar to that of a Dark Jedi.

Max does not play a death animation when killed. Instead, he just plays the same idle animation when he is first found, but takes on the attributes of a corpse, such as lack of collision. However if he is activated like a switch or door, he will get out of the chair and approach the room's door to exit, waiting for you to open it for him. Upon doing so, he will then wander the level, killing enemies and villagers alike. After Max has been let outside, the player can activate him again, letting them see from his view. A HUD message is also displayed reading, "It's MaxVision™!" If he is attacked by the player, he will return fire. If the player pushes Max outside instead of activating him, and attacks him, he will not fire back. If he is killed after being activated, he will freeze standing instead of playing any animation, but still becomes a corpse.

Max makes a second cameo appearance in Level 9 "Fuel Station Launch". During the final jump at the end of the level, you need to quickly snap back the mouse just before you land so you are facing backwards, which will allow you to see Max's face plastered three times on the front of the platform you just jumped off.
