Even with its multilayered mysteries and bizarre developments, film noir was always more about style than plot. No one can tell you what The Big Sleep is about, but everyone remembers Bogart’s rumpled trench coat/fedora combo and Bacall’s sharp houndstooth suit.
Kimberly Truhler surveys film noir style in her new book Film Noir Style. This is more than an analysis of the costumes the actors wore in films such as The Postman Always Rings Twice and Gilda, though it is that. Truhler occasionally discusses how lighting, set design, and camera angles fashioned the instantly identifiable noir aesthetic.
