fwiw, film, like painting, is not necessarily realistic.

It would be erroneous to recolor each scene towards realism. Realism might not be the intent of the film maker.

I concur. Trying to color correct scene-by-scene is probably not the answer (and would take a LOT more time). Though perhaps a reel-by-reel effort might not be unreasonable?

On a seperate note, I was just watching this, and perhaps the "ESB is very blue" theory might not be too far off: http://www.youtube.com/watch?v=wMya5Z96VA8
