L.A. Confidential is a 1997 American neo-noir crime film directed, produced, and co-written by Curtis Hanson. The screenplay by Hanson and Brian Helgeland is loosely based on James Ellroy's 1990 novel of the same name, the third book in his L.A. Quartet series. Like the book, the film tells the story of a group of Los Angeles Police Department (L.A.P.D.) officers in 1953, and the intersection of police corruption and Hollywood celebrity. The title refers to the 1950s scandal magazine Confidential, portrayed in the film as Hush-Hush. Wikipedia
