A 1929 Mind Screw short silent film made by Luis Buñuel and Salvador Dali, the father of cinematic Eye Scream, a milestone on surrealist cinema, a Real Life example of True Art Is Incomprehensible and of course of Le Film Artistique and the plot -- it's indescribable at best. The title translates to An Andalusian Dog, which if anything just makes it more confusing (Dali's friend Lorca was an Andalusian, and they had a falling out around the production of this film, so the title is a Take That at Lorca).
