The cell block on the Death Star, when shown in a straight-down-the-barrel shot, has a slightly different perspective angle and vanishing point, making it more realistic. Very subtle.

Yeah, in previous versions, there had been a matte painting back there that didn't quite line up with the perspective presented by the actual practical corridor. It's extremely hard to notice. I never did before. It's not that bad, and that's why its correction is so easy to miss.

I guess that's why I never noticed it then.

Thanks for the info- I'll have to check that out.
