One of Cortazar's best known short stories, "Las babas del diablo," was adapted by Michelangelo Antonioni in 1966 into an internationally recognized film entitled Blow-up. Starring Vanessa Redgrave, David Hemmings and Sarah Miles, the film explores the theme of illusion and reality. A photographer (Hemmings) has taken a photo of what he believes was a murder; Redgrave suspiciously tries to seduce him out of the negative.
