The film is a hybrid of melodrama and film noir (dark and moody themes and visual style)
Produced by Warner Bros- known for tough detective films and neo-noir films.
The Hays Code/ Production Code from 1934-1954 set moral guidelines to prevent the government banning or censoring the films, and so the language in the film is very tame.
Films had to uphold moral standards and the 'correct standard of life'.
