Author James Ellroy's pitch-black examination of Hollywood history focuses on the infamous 1947 murder of wannabe actress Elizabeth Short. Josh Hartnett and Aaron Eckhart play the Los Angeles detectives assigned to the case. Scarlett Johansson and Hilary Swank are just a couple of the fatal femmes whose paths they cross. Director Brian De Palma (Mission: Impossible, Scarface) keeps things glossy and pulpy, but the cast isn't all it's cracked up to be. Not as good as the last Ellroy adaptation, L.A. Confidential, but a classy bit of film noir nonetheless.121 minutes R.
