Sal­vador Dalí and Luis Buñuel report­ed­ly car­ried rocks in their pock­ets dur­ing the pre­miere of their first film Un Chien Andalou, antic­i­pat­ing a vio­lent reac­tion from the audi­ence.

It was a fair con­cern. The movie might be almost 90 years old but it still has the pow­er to pro­voke – the film fea­tures a shot of a woman get­ting her eye slashed open with a straight razor after all. As it turned out, rocks weren’t need­ed. The audi­ence, filled with such avant-garde lumi­nar­ies as Pablo Picas­so and André Bre­ton liked the film. A dis­ap­point­ed Dalí lat­er report­ed that the night was “less excit­ing” than he had hoped.

Un Chien Andalou fea­tured many of Dalí’s visu­al obses­sions – eye­balls, ants crawl­ing out of ori­fices and rot­ting ani­mals. Dalí delight­ed in shock­ing and incit­ing peo­ple with his gor­geous, dis­turb­ing images. And he loved grandiose spec­ta­cles like a riot at a movie the­ater.

Dalí and Buñuel’s next movie, the caus­tic L’Age d’or, exposed the dif­fer­ences between the two artists and their cre­ative part­ner­ship implod­ed in pre-pro­duc­tion. Buñuel went on to make a string of sub­ver­sive mas­ter­pieces like Land With­out Bread, The Exter­mi­nat­ing Angel and The Dis­creet Charm of the Bour­geoisie; Dalí large­ly quit film in favor of his beau­ti­ful­ly craft­ed paint­ings.
