OK, I'm sorry, but THAT is frickin' sweet.
Here's my guess:
1. Swapped out the Maul model with the Obi-Wan model, the anim order is different, so one of Maul's animations is actually replaced by Obi's death anim.
2. Used the 'iamquigon' cheat to replace Obi-player with Qui-gon.
3. Got the camera 'stuck' in the cutscene view.
HOW you accomplished this, however, is an entirely different animal. My hat is off.
