Blowup (also rendered as Blow-Up) is an award-winning 1966 British-Italian art film directed by Michelangelo Antonioni, his 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" by Argentinian writer Julio Cortázar, and by the work, habits, and mannerisms of Swinging London photographer David Bailey.
