North By Northwest...

[Robert Harris]

How does vistavision 8perf 35mm run horizontally and cropped to 1.85:1 compare to 70mm 5perf cropped to 1.85:1 in terms of image fidelity?

IMDB technical lists several aspects NxNW has been shown in:

• 1.66 : 1(intended & European theatrical ratio)
• 2.00 : 1(Univisium, alternative US theatrical ratio)
• 1.50 : 1(VistaVision, original & negative ratio)
• 1.85 : 1(intended & US theatrical ratio)

When doing a restoration from 8perf vistavision sources, to digital intermediate, to 70mm re-print. How does one decide what aspect to make the 70mm?

The film was designed to be screened at 1.85.
