The film was shot in the style of a hard-boiled 1950s American film noir, or its descendant, the neo-noir genre. Many themes include noir references such as film posters in sets, angular, high contrast lighting and the characters’ struggle with their illicit passions. However, like most Almodóvar films, it is filmed in bright color rather than the black-and-white emblematic of noire.
