Blowup

Blow-Up (sometimes styled as Blowup or Blow Up) is a 1966 psychological mystery film directed by Michelangelo Antonioni, co-written by Antonioni and Tonino Guerra and produced by Carlo Ponti. It is Antonioni's first entirely English-language film and stars David Hemmings, Vanessa Redgrave and Sarah Miles. Also featured was 1960s model Veruschka. The plot was inspired by Argentine writer Julio Cortázar's 1959 short story "Las babas del diablo".

The story is set within the contemporary mod subculture of Swinging London, and follows a fashion photographer (Hemmings) who believes he has unwittingly captured a murder on film. The screenplay was by Antonioni and Tonino Guerra, with English dialogue by British playwright Edward Bond. The cinematographer was Carlo di Palma. The film's non-diegetic music was scored by American jazz pianist Herbie Hancock, and the English rock group The Yardbirds are seen performing "Stroll On".

In the main competition section of the 1967 Cannes Film Festival, Blow-Up won the Palme d'Or, the festival's highest honour. The American release of the counterculture-era film with its explicit sexual content defied Hollywood's Production Code, and its subsequent critical and commercial success influenced the abandonment of the code in 1968 in favour of the MPAA film rating system.

Blow-Up would influence subsequent films, including Francis Ford Coppola's The Conversation (1974) and Brian De Palma's Blow Out (1981). In 2012, Blow-Up was ranked No. 144 in the Sight & Sound critics' poll of the world's greatest films.
