Exorcist Steps to Get Special Plaque, Oct. 30

Perhaps the most famous movie about Georgetown will be commemorated Oct. 30 by a special plague at the so-called Exorcist Steps at 36th and M Streets. The steps down to M Street from Prospect Street figured in the climatic scene of the 1973 film “The Exorcist,” when the priest sacrificed himself for the girl possessed by the devil, leaping from a window in a Prospect Street home and tumbling down the steps to his death.

Andrew Huff is coordinating the event in collaboration with the D.C. Office of Motion Picture and Television Development, the Executive Office of the Mayor, the Dupont Festival and Councilmember Jack Evans, at whose office he worked. On hand at the event, he says, will be the film’s director William Friedkin (4 p.m.; top of the steps). The plaque dedication ceremony (6 p.m.; bottom of the steps) and a screening of “The Exorcist” (7:30 p.m., Georgetown AMC) will follow.
