Michelangelo Antonioni's seminal 60s classic tells the story of fashion photographer Thomas (David Hemmings) who takes a voyeuristic shot of a man and a young woman in each other's arms in a park. The young woman (Vanessa Redgrave) follows Thomas home and makes love to him in exchange for the photograph. But Thomas keeps the negative, and when he enlarges it, what had seemed a carnal moment appears to be murder. Thomas returns to the park, and discovers that the man in the photograph is dead. Yet when Thomas enlarges the photo again, he notices a shadow in the bushes that could be barrel of the gun. Is the woman with whom Thomas made love a murderer? Reality seems to change with each Blow-Up.
