Blowup (sometimes styled as Blow-up or Blow Up) is a 1966 mystery thriller film directed by Michelangelo Antonioni and produced by Carlo Ponti. It was Antonioni's first entirely English-language film, and stars David Hemmings as a London fashion photographer who believes he has unwittingly captured a murder on film. The film also stars Vanessa Redgrave, Sarah Miles, John Castle, Jane Birkin, Tsai Chin, Peter Bowles, and Gillian Hills, as well as 1960s model Veruschka.


The narrative covers a day in the life of a glamorous fashion photographer, Thomas (Hemmings), the character's creation being inspired by the life of an actual "Swinging London" photographer, David Bailey, and contemporaries such as Terence Donovan, David Montgomery and John Cowan.
