Yeah, I guess even the other "in Mos Eisley" parts kind of look like that.
I wonder if they processed all the stuff at the same time? If so, could their color developing bath have been too hot? I know I intentionally boil (not literally) my B/W negs to increase grain, and I know that has an effect on color film too - I wonder if they rushed development of stuff run through the optical printer? Mike, are the shots you're talking about at Elstree run through the compositor/optical printer at all?
