The plot still makes no sense whatsoever, even 70 years since its release. What does make sense is just how steamily sexy and fun this film is. Everyone knows how brilliantly Humphrey Bogart and Lauren Bacall simply bounce off each other, and they do so magnificently in The Big Sleep. Howard Hawks fills the film with great scene after great scene, most of them involving the two stars, but there are a few excellent cameos – the best one involving Dorothy Malone flirting in a bookstore. In fact, the greatness of the individual scenes is also the film’s biggest problem: it is only when Bogart sits down and tries to figure out the plot that the film drags.
