A quick question...
I don't know if it is a continuity error or something else, but it appears that there is a discrepency in the grime and dirt on the panel where the restraining bolt is attached to R2. The Tantive IV shots show R2 with a relatively clean panel. The Tatooine footage has the panel much darker with a spot already wiped off for the bolt even before he is captured by the Jawas. More of me being nit-picky, but is seems that the wiped of area shouldn't appear until after he gets the bolt. This make sense? I'm not at home so I can't post any screencaps.
