Paris, 1929: The premiere of the short silent surrealist film "Un Chien Andalou" (An Andalusian Dog) by Louis Buñuel and Salvador Dalí. The beginning of the film with the girl’s eyeball being slit with a razor is for me the most shocking and offensive sequence of a film ever. The murder shower scene in "Psycho" was shocking and offensive too, but maybe the most shocking and offensive sequence was in the Lumière brothers film, shown in Paris in 1895: "L'arrivée d'un train en gare". They say that the audience jumped back from the screen as if they were going to be run over by the oncoming train. Years after that, we are all long experienced with films, and even "Jaws 3D" which was supposed to be viewed with those cardboard polarized glasses to create the strong illusion of the shark eating the man, was more funny than shocking.
