Where many of Peter Greenaway’s earlier films were obsessed with the picture/photographic frame, in his more recent work all the world’s a stage. His latest feature, The Baby of Mâcon, is a three-act cathedral play performed before an audience that enters into the action. This no doubt sardonic parable—which at last report lacked an American distributor and failed to make a Hirshhorn engagement last spring—centers on a small, dying French town where the birth of a baby boy is seen as a sign that a curse on the place has been lifted. Tonight and Saturday at 8 p.m. at the Hirshhorn Museum & Sculpture Garden’s Ring Auditorium, 7th & Independence Ave. SW. FREE. (202) 357-2700. (MJ)
