Haven't seen this mentioned before but has anyone ever noticed in the Emperor's arrival scene featuring the shot of the hundreds of troopers shown from above that the 4th trooper from the left, front row, with back to the camera (the TK looking up and to his right) had his head animated to look down and pan with the Emperor's party as thay pass? This is interesting as this particular trooper is part of the hand painted matte painting that was used to create the copious amount of troops needed for this shot. In the original 1983 version he does not move. It was a little add in for the Special Edtion from '97.
