After years of watching these films the only things I've noticed are:
The R5-D4 thing - one minute he's there, the other he's not....
The one thing I've seen that not many have picked up on is...actually theres 2...is
in ESB......just after the heroes have escaped Cloud city and Vader is talking to his officers on the Star Destroyer...Piett and the dopey looking fuck are on about actvating the tractor beam...Well their medals on their outfits are on the wrong side..the Mirror thing again..
That also happens with Han and Lando in Jedi...When Han is talking to Lando about the Falcon...
But the thing I've noticed that not many people have is in Jedi........
When the Ewoks have hold of our heroes.....In the village when Luke is doing his levatating thing with 3PO...Watch R2...One minute he's tied up with ropes..then he's not, then he is agian...then he's set free by Teebo
.....Thats the onyl real thing I've seen.......Oh and also in Jedi........shit I've forgotten.....thats class A on a friday night for ya!!
