Making a documentary about a living person is much different from creating one about a historical figure, but acclaimed documentarian Perry Miller Adato shows how each is done with two short films about American women artists—separated by half a century—whose work is currently on display at the Corcoran. Mary Cassatt is a study of the impressionist who came to prominence in France, and Helen Frankenthaler: Toward a New Climate investigates the abstract expressionist who pioneered the stained canvas. After presentations of the films, Adato will join a discussion of her work—and Cassatt’s and Frankenthaler’s. At 7:30 p.m. at the Corcoran Gallery of Art’s Hammer Auditorium, 17th & New York Ave. NW. $15. (202) 639-1770. (Mark Jenkins)
