Incident at a showing of TDtESS
Back some decades ago, I went with a friend (who was enrolled there) to see a screening of TDtESS in a lecture hall at MIT. The audience was, as you might guess, largely made up of people who loved the film and rarely got a chance to see it in those pre-home-video days.
But there was one fellow in the back row who kept jeering loudly at anything he considered illogical. For example, when the soldiers say they can't penetrate Klaatu's spaceship "even with a diamond drill," he hooted that they should have tried a certain other material, ignoring the fact that the movie had been made in 1951 and was set in 1951, so the other stuff hadn't been invented yet.
He got to be a real pain, till finally a fellow in the front row stood up, turned around and bellowed, "Shut UP!! Ain't you got no RESPECK!!?" The audience broke into cheers and applause, and the heckler wasn't heard from again.
