I think there are about three people who haven't seen this movie, if you are one of them you should get yourself a copy immediately and watch it.
It not only was a launching vehicle for the careers of Guy Pearce (Who I love!) and Russell Crowe, but it also has that other adorable Australian, Simon Baker. He's only in it for a few scenes, but he's there.
L.A. Confidential is, like most of the books by the incredibly talented writer James Ellroy, a sweeping tale of several crimes and the three cops that have to work together (or apart) to solve them. It also has an incredible "Holy shit! I didn't see that coming" moment.
Just go rent it.
