The Big Sleepis the best example of a classic Warner Bros.mystery.It is a very complex, confusing, logic-defying whodunit with a quintessential private detective (Marlowe), false leads, unforgettable dialogue and wisecracks, raw-edged characters, sexy women (including the two daughters of a dying millionaire, a bookseller, and others), tough action, gunplay, a series of electrifying scenes, and screen violence.Only a small number of freed, rebellious humans really lived in he real world - in a deep underground city and refuge known as Zion.The straight-forward narrative is told and seen mostly hrough the eyes of the young impressionable hero, who idolizes a mysterious, gunslinging hero from the wilderness who appears from nowhere - a man without a past or a future.In the next memorable scene of pantomime, Pinky is whistling the previous tune while feeding a bunch of flowers to himself and to his horse on the dog-catcher cart.
