I like the comparison, but I will say something about that overly blue 70mm frame.

I'm not sure if that 70mm scan is accurate to how the film would have looked in a theater. Though most of them don't seem to have visible fading (possibly LPP?), we don't know what kind of post-processing was done by the person who scanned them. If they were auto-corrected in the scanner software or some other image editing program, then the brightness, contrast, gamma, saturation, and/or color balance may not reflect the colors on the actual film.

For example, here's the Jedi1.net scan of the bacta tank wide shot:

Now here's an image of a cell of a different frame of the same shot, which I found on eBay:

Notice how the ceiling isn't as green. To me, the lower image looks more balanced. I think the Jedi1.net image had some kind of auto-correct or something. And I'm not sure if even that reflects the "correct" color balance of the film - this was taken by a digital camera, and I'm not sure how the film cell was illuminated (though the light behind the clear areas *looks* correctly white...

Since this really doesn't have anything to do with this project, I'll talk more about the film cells in the Color Timing and Cinematography thread.
