It is regarded as an early example of British film noir, with the kind of subject matter and filming style which fell completely out of favour during the war years – when British studios felt that cinemagoers would want either light entertainment and escapism or topical patriotic propaganda pieces – and would not be taken up again until the later 1940s.
