Dynamic duo William Faulkner and Jules Furthman scripted this Howard Hawks classic starring Humphrey Bogart and Lauren Bacall (who, rumor has it, fell in love on the set) that's supposedly based on an Ernest Hemingway tome. Bogie is Harry Morgan, a charter boat owner who falls for Bacall's seductive petty thief, Marie Browning. Can't-miss scenes include the now-legendary "You know how to whistle, don't you?" exchange between Bogie and Bacall.
