Blow-Up is a 1966 British-Italian mystery thriller film directed by Michelangelo Antonioni about a fashion photographer, played by David Hemmings, who believes he has unwittingly captured a murder on film. It was Antonioni’s first entirely English-language film.

In the main competition section of the Cannes Film Festival, Blowup won the Grand Prix du Festival International du Film, the festival’s highest honour.

Film critic Andrew Sarris said the movie was “a mod masterpiece”. In Playboy magazine, film critic Arthur Knight wrote that Blowup would be “as important and seminal a film as Citizen Kane, Open City and Hiroshima, Mon Amour – perhaps even more so.” Even film director Ingmar Bergman, who generally disliked Antonioni, acknowledged its significance: “He’s done two masterpieces, you don’t have to bother with the rest. One is Blow-Up, which I’ve seen many times, and the other is La Notte, also a wonderful film, although that’s mostly because of the young Jeanne Moreau.” Source: Wikipedia
