WTOP Entertainment Reporter Jason Fraley celebrates Halloween with an hour-long conversation with Oscar-winning filmmaker William Friedkin, who directed arguably the scariest movie of all time in “The Exorcist.” They spoke in 2015 when Friedkin came to Washington D.C. to dedicate the Exorcist Steps as an official historical landmark in Georgetown. They also discussed his journey from directing TV episodes of “The Alfred Hitchcock Hour” to Best Picture winners like “The French Connection.”
