These are really interesting observations to me, in part because I am a film scholar and one of the films I'm researching, Berkeley Square, a 1932 time-travel film starring Leslie Howard, is essentially lost--only non-screening silver nitrate prints remain. Also recalls for me some of the memorative functions of restoring old theaters, which always seem nostalgic for earlier modes of cinematic production. Kari's observations recall for me one of the more profound moments of Chris Marker's amazing cinema-essay, "Sans soleil," in which the voice-over narrator reflects that cinema itself is a memory machine, one that in ways depends on forgetting.
