The color timing on GF I and II was indeed a huge difference especially in daylight scenes on GF I. But that was done from extensive research by Robert Harris, all the original materials they could get their hands on and by working with the Prince of Darkness himself Gordon Willis.

Brilliant restoration job on both films, in fact some of the best done in the past few years....And of course no worked on the mono tracks. Go figure.

North By Northwest has different timing on every release I've seen. The new version looks far more like film than the Lowry DVD snafu that was downright pinkish throughout, but still doesn't exactly sway me 100%. (It was an 8K scan however) The old Criterion issue used a show print and looks like what a print would have on release.
