Filmfest DC has added a couple of screenings to its schedule "due to popular demand"—Ballerina, a documentary on five Russian dancers, and AmericanEast, which our Jule Banville praised in our guide to the fest, writing, "who needs subtle when you've got a message–and a cast talented enough to get it across?" Both films screen Saturday at the Avalon at 2:30 p.m. —Mark Athitakis
