Un Chien Andalou (1929)

“A surrealistic film with input from Salvador Dalí, director Luis Buñuel presents stark, surrealistic images that shock the viewers including the slitting open of a woman’s eye and a dead horse being pulled along on top of a piano. Obviously open to interpretation – from deep meanings to it all meaning absolutely nothing – it is certain that this short (17 minutes) film presented something new in the cinema of its day.” — IMDb.com
