Here's another minor detail that bothers me in ESB:

IG-88 is a pretty cool looking droid/bounty hunter. His appearance is brief, but cool nonetheless. I'm sure some of you agree? While the head is a reused part from ANH (from the cantina), it doesn't take anything away from the look of the character.

However, an identical droid can be seen (for the sake of avoiding the EU, I would assume it is a different droid but same model) in the background of the scene when Chewie is trying to rescue C-3PO's parts from the Ugnaughts. The problem with this identical droid is the color, or shall I say LACK OF COLOR on it. It is totally obvious that it is an unpainted IG-88 that was placed there as a prop. The IG-88 seen in the bounty hunter lineup looks metallic, as a droid should. But without the paint job, the droid seen on Cloud City looks like a big plastic model, and nothing more!

The droid itself doesn't move in any of the shots, so I think it might not be too difficult to color it a metallic color to match up with IG-88, instead of looking like an Ugnaught's lifesize plastic replica of IG-88 (collect them all!)

Not a big deal? Perhaps. But it is one of those things that has bothered me every time I see it, ever since I first noticed it (I'm talking YEARS now).
