Unusual (or extreme) aspect ratios?

Looking through my DVD collection the other day and noticed a few movies had odd aspect ratios. For example Lawrence of Arabia (2.20:1), Bridge on the River Kwia (2.55:1) and a few others. I was wondering if anyone else knew of some movies that have unusual aspect ratios (not 1.33:1, 1.66:1, 1.78:1, 1.85:1, or 2.35:1)

Ben Hur was 2.76:1. It was filmed 2.2:1 65mm, with an anamorphic lense. I'm afraid I can't recall the name of the process right now.

Also, the battle scene in Gance's Napoleon was at least 3:1.

All "scope" projected films post-1971 are 2.40:1.
SMPTE 195 specifies that the proper projection AR for scope films is actually closer to 2.39:1. the SMTPE 195 aperture is actually .825" x .690" which, when multiplied for anamorphic projection and divided as a ratio, comes out to 2.39130434.... this is usually referred to as 2.4:1, but 2.39 is a closer approximation. this was a slight change from the 1971 standard (PH22.106-1971), which had an aperture of 0.838 X 0.700 (or 2.39428571... when fixed for anamorphic projection and divided as a ratio).

Early Cinemascope was 2.55:1.

Most of the 65mm processes were in & around the 2.20/2.21:1 area.

Try 4:1. That's three Academy ratio frames side-by-side!
Didn't know when the Academy format was adopted, but I stand corrected...or, clarified. Something like that.

This should be required knowledge at the Home Theater Forum.
Actually, it's 2.39:1.

The 1971 0.838 x 0.700 projection aperture was changed under SMPTE 195 in 1993 to 0.825 x 0.690. The AR remained 2.39:1.
