Blowup (as shown in the screen credits, also often rendered as Blow-Up on promotional and packaging materials) is a 1966 British-Italian art film directed by Michelangelo Antonioni and was that director's first English language film. It tells the story of a photographer's involvement with a murder case. The film was inspired by the short story "Las Babas del Diablo" ("The Droolings of the Devil") by Argentinian writer Julio Cortázar, and by the work, habits, and mannerisms of Swinging London photographer David Bailey. The film was scored by jazz pianist Herbie Hancock, although the music is diegetic as it is played on a record by the main character. Nominated for several awards at the Cannes Film Festival, Blowup won the Grand Prix.Blowup stars David Hemmings, Vanessa Redgrave, Sarah Miles, John Castle, and Jane Birkin.
Blowup was controversial as the first British film to feature full frontal female nudity (although this is sometimes noted as having happened in the slightly later if....). MGM did not gain approval for the film under the MPAA Production Code in the United States. The code's collapse and thorough revision was foreshadowed when MGM released the film through a subsidiary distributor and Blowup was shown widely in North American cinemas.
