Niagara is a 1953 American noir[3][4] thriller[5] film directed by Henry Hathaway and produced by Charles Brackett. Unlike other films noir of the time, which were typically black-and-white,[3] Niagara was shot in “three-strip” Technicolor. In the weeks after Monroe’s death in August 1962, Andy Warhol used a publicity photo from Niagara as the basis for his silkscreen painting Marilyn Diptych.
