Through their accomplishment with "Un Chien Andalou", Dalí and Buñuel became the first filmmakers to be officially welcomed into the ranks of the Surrealists by the movement's leader André Breton, an event recalled by film historian Georges Sadoul: "Breton had convoked the creators to our usual venue Café Radio ... one summer's evening. Dalí had the large eyes, grace, and timidity of a gazelle. To us, Buñuel, big and athletic, his black eyes protruding a little, seemed exactly like he always is in "Un Chien Andalou", meticulously honing the razor that will slice the open eye in two."
