Elsa Dorfman and her unique photography are profiled in Errol Morris’ latest film. (Elsa Dorfman)

‘The B-Side: Elsa Dorfman’s Portrait Photography’
Documentarian Errol Morris is gifted when interviewing big names like Robert McNamara in “The Fog of War” and Donald Rumsfeld in “The Unknown Known,” but his best work comes in small — or at least moderate — packages. “The B-Side: Elsa Dorfman’s Portrait Photography” is a lovely, heartfelt look at Dorfman, now 80, who became known for her 1974 book “Elsa’s Housebook: A Woman’s Photojournal,” which combined self-portraits, many of them meditations on feminism, with portraits of others. Using a Polaroid camera that instantly produced 20-by-24-inch prints, she would take only two shots of each subject. They got to choose one, while she kept the other (the “B-side” of the title). It’s a soft, quiet kind of movie about art, inspiration and a woman with a unique vision.

‘Genocidal Organ’
In these trying times, it’s nice to escape into the cheerful world of anime. “Genocidal Organ,” based on the novel by Project Itoh (the pen name of the late Japanese sci-fi writer Satoshi Ito), takes place after a bomb destroys Sarajevo. Heightened surveillance helps the U.S. and other developed countries survive, while the unlucky ones find their countries are in the midst of mysterious genocides — all linked back to one American. It’s a rare, one-night-only showing, so clear your calendar.
Angelika Pop-Up at Union Market, 550 Penn St. NE; Thu., 7 p.m., $10.50. Angelika Film Center at Mosaic, 2911 District Ave., Fairfax; Thu., 7 p.m., $15.

‘Cinema de la revolution: America Films 18th-Century France’
Democracy has its problems, but our political stories rarely end at the guillotine. See why that’s good at “Cinema de la revolution: America Films 18th-Century France,” the National Gallery of Art’s summer film series. Not all of the six movies end headless — “Dangerous Liaisons” and “Jefferson in Paris” are two that don’t — but you can also catch Sofia Coppola’s underrated 2006 film “Marie Antoinette” and the 1935 version of “A Tale of Two Cities.” Sorry, but no cake is allowed in the theater.
National Gallery of Art, East Building, Fourth Street and Constitution Avenue NW; Fri.-Aug. 12, various times, free.
