So This Is Paris comes to us in a new print from the Library of Congress, preserved in 2014 from a nitrate print, part of a collection acquired from United Artists in 1970. This print replaces a worn ("beloved") safety preservation from the same source made 39 years prior.
I haven't heard anything yet regarding Strike, but I expect we'll see a black and white print, hopefully with the original Russian titles (they are a graphical element of the film). We may lose a portion of the left side of the image as Soviet films were commonly printed in later years with a sound aperture even if they were silent and had picture in the soundtrack area. But this is mere speculation.
Next up, the first of the day's seriously incomplete films, Anders als die Andern, whose homosexual content overstretched Weimar tolerance. All that exists is a 45 minute excerpt included in a later documentary, The Laws of Love, which survives in a Russian print. The reconstruction we'll see includes some supplementary material to fill in the gaps. It was done photochemically, on black and white stock with some tinted sections.
Not much is known about the print screening of The Last Command. There was a new print around 2008 but my Paramount contact doesn't think this is it. I have no reason, however, to doubt its bona fides.
As you've guessed by now, Sadie Thompson is the second seriously incomplete film. When the sole surviving print was discovered in Gloria Swanson's estate, the last reel was a goner. A patchwork strategy using the script, stills, and footage from a later adaptation of Maughm's story will at least help wrap up the narrative. This reconstruction was undertaken in 1987, before the digital era, so we needn't worry about that sort of thing.
Thanks to Jack Durwood, Mike Mashon, and Todd Wiener for doing their best to field my questions.
