Memorable Movie-going Moments

An old writer told me about seeing EASY RIDER in 1968 or '69 at the Grandin Theater in Roanoke, Virginia. As the movie ended, with Hopper's and Fonda's characters lying dead, a hippie stood up in the front of the theater and said, "YOU SEE THAT! YOU killed those boys!" A redneck in the back of the theater hollered back: "You shut the hell up, boy, or we gonna kill you next!"

Whatever happened to that kind of audience participation? The kind that didn't involve cellphones?
