No, Auslanders, the National Mall is not, as many surmise, a gigantic shopping mall. But for the occasional National Football League-slash-Pepsi promotion, we do prefer to keep the National Mall free of branding. However, once a year, the Mall at 15th and Constitution Avenue goes multiplex, presenting a series of film classics called Screen on the Green. And whether you’re a film buff, an enthusiast of DC’s green space, or simply a summer intern looking to cop a feel under the setting sun, this annual festival has something for everyone.
