>> The National Gallery of Art‘s series on Czech filmmaker František Vláčil kicks off this weekend with two films. His small body of work stands out from the gritty Czech new wave films of the era and, not surprisingly, was seen as subversive by censors in his native Czech Republic. Thwarted after the 1968 Soviet invasion, Vláčil (1924-1999) maintained that he was only interested in “pure film” and applying poetic license to shape allegory out of ancient tales. Sunday at 2:00 p.m., see The Devil’s Trap, the first of Vláčil’s three historical-allegorical epics. In a drought-stricken Bohemian village, a church inquisitor probes the local miller to find out if his flourishing grain mill is the work of the devil. At 4:30 p.m., watch Markéta Lazarová, which Vláčil based on Vladislav Vančura’s best-selling 1931 novel, in turn based on a story handed down within Vančura’s family. Attempting to recreate the mood of medieval society, sets and costumes were even made with traditional tools, and actors tried to portray the raw and unfiltered emotions that presumably prevailed.

>> Opening at Washington Printmakers this weekend, see Both Sides of the Brain. a traveling international mezzotint portfolio curated by Aaron Coleman. Mezzotint requires hours of physical labor “rocking” a copper plate with a special toothed tool to create an all-over texture, which holds the ink so few artists work with this technique. View the work of the brave artists that do at the opening reception on Saturday from 1 to 4 p.m.

>> The Fridge opens the first solo show from Asad “ULTRA” Walker, a D.C. graffiti artist who has been creating work for 30 years.
