Beauty and the Beast’s CAPS source ratio is 1.66, yes, but it was hard matted to 1.85 on 35mm as the directors intended. There’s a preservation project currently in progress for an Italian print somewhere on this site with the same ratio. The only way you can see the film as close to the original CAPS ratio as possible in HD is through the 3-D Blu-ray. Same for Lion King.
Thanks for the info. Do you know how many of these titles have been scanned and available?
