Out of all their silent releases, these are what were restored in 4K resolution:FrauBlucher wrote: Fri Aug 13, 2021 8:16 pm What's the chances that Criterion or anyone else release silent films in UHD?
The Cameraman - 35mm safety fine-grain positive, 35mm duplicate positive (of The Big Parade of Comedy), 16mm print
The Kid Brother - 35mm unspecified fine-grain positive (created from the nitrate camera negative)
Speedy - 35mm safety fine-grain positive, 35mm preservation negative
The Kid - 35mm nitrate camera negative (likely reassembled from B/C negatives), 35mm nitrate fine-grain positive
I remember reading somewhere there's a few newer restorations of Chaplin's films, so I'd expect Modern Times to be high on the list (especially since even the 2010 Blu-ray looks quite lovely). Even though Safety Last! has its best surviving material as an original 35mm nitrate print, having seen it in 35mm, it would also be a great candidate.
