A wonderful segment of CBS This Morning, devoted to the assiduous efforts by film curators, technicians, and other professionals of The Museum of Modern Art, toiling to restore gone-missing movies, scanning and cleaning cans of crumbling celluloid to pristine, viewable condition. Curators Raj Roy and Dave Kehr, interviewed at MoMA’s off-site film facility in eastern Pennsylvania (which resembles a bunker out of DR. STRANGELOVE) describe the archive’s mission and anticipate the soon-completed restoration of a Mary Pickford film, ROSITA (1923), the first American directorial effort of Ernst Lubitsch.
