Simpsons castmember -- voice of Mr. Burns, Waylon Smithers, Ned Flanders and Principal Skinner, among others -- and New Orleans resident Harry Shearer will appear at a screening of his documentary The Big Uneasy about Hurricane Katrina, co-sponsored by the DC Labor FilmFest and the Project on Government Oversight. Shearer speaks to investigators and a whistleblower from the Army Corps of Engineers, revealing that some of the same flawed methods responsible for the levee failure after Katrina are being used to rebuild the system expected to protect the new New Orleans. Tuesday, March 15, at 7 p.m. AFI Silver Theatre, 8633 Colesville Road, Silver Spring. Tickets are $11 general admission. Call 301-495-6720 or visit afi.com/Silver.
