For the last 22 years, the Cinematheque has partnered with the Film Noir Foundation on its longest running festival, Noir City: Hollywood, that celebrates the history of film noir. Nitrate Nights, one of The American Cinematheque’s newer film festivals, offers rare chances to see films on 35mm nitrate film base, a format abandoned in the early 1950s due to its highly flammable quality. After being retrofitted to project nitrate safely in 2016, the Cinematheque has since partnered with such film archives as the George Eastman Museum, the Library of Congress, the Academy Film Archive and the UCLA Film and Television Archive to bring rare archival prints to the screen for the public.
