Robert Altman’s “The Long Goodbye” (1973) attacks film noir with three of his most cherished tools: Whimsy, spontaneity and narrative perversity. He is always the most youthful of directors, and here he gives us the youngest of Philip Marlowes, the private eye as a Hardy boy. Marlowe hides in the bushes, pokes his nose up against a window, complains like a spoiled child, and runs after a car driven by the sexy heroine, crying out “Mrs. Wade! Mrs. Wade!” As a counterweight, the movie contains two startling acts of violence; both blindside us, and neither is in the original Raymond Chandler novel.
