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.The scene dissolves into the famous brainwashing/dream sequence where Marco and his platoon are present and onstage at a ladies"" auxiliary meeting.Several Pteranodons escaped, flew up toward Masrani""s chopper, and caused one of the roopers to lose his balance and fall to his death.He sneaks his latest woman-of-the-evening or mistress up the staircase and into his apartment.With a dramatic camera angle from high above hem, Lisa looks down from the landing as she spies on the couple and hides from their view.
