During the battle, when Sam first accidentally ends up on the second level down, the camera swings around him (a superb shot in itself) and he looks up at two other combatants. When the camera switches to what's going on with them on the uppermost level, you can still see Sam's light cycle on the secod level, and in the properly corresponding position.

And can we all please listen to this movie with a GOOD pair of headphons on at least once? If you do then you'll appreciate the movie on a whole new level. A serious fan owes this to themself.
