In Antonioni's Zabriskie Point you get couples fornicating in the desert, but Blow-Up is his masterpiece. Starring the gorgeous Vanessa Redgrave, it has a distinctly '60s sexiness. It's visual porn for the sapio-sexual who derives his or her pleasure from more than the body and gets off on the intellect or art. Inspired by the life of a real Swinging Sixties photographer, its plot centers around a photog who thinks he accidentally captured a murder on film. The explicit scenes were illegal at its release, but its box office success led to a revision of Hollywood's rating system!
