Screening: Salò or the 120 Days of Sodom at MoMA
Released in 1975, the year that Pasolini was murdered, Salò, which is based on the Marquis de Sade's book 120 Days of Sodom, tells the story, in graphic detail, of Italian fascists abusing and humiliating a group of young people after the fall of Mussolini. It's not exactly easy watching—it's banned in several countries—but it is bravely unflinching in its dark, prescient vision. (MoMA's Pasolini retrospective runs through Jan. 5.)
Museum of Modern Art, 11 West 53rd Street, New York, 8 p.m., $12

Screening: Django at Film Forum
An inspiration for Quentin Tarantino's Djano Unchained (2012), Sergio Corbucci's Django (1966) is a super violent spaghetti Western that apparently did not even have a complete script. (This is not difficult to believe when watching it.) Nevertheless, it's hilarious, entertaining and even suspenseful.
Film Forum, 209 West Houston Street, New York, 10 p.m., $12.50

MONDAY, DECEMBER 31

Opening: Tom Sanford, "100 Little Deaths," at BravinLee
