A masterful blend of comedy, romance, and action, Howard Hawks' To Have and Have Not is filled with the director's signature situations and relationships. The characters could have been lifted from any one of a number of Hawks films: a strong, stoic hero (Humphrey Bogart), a clueless sidekick (Hawks regular Walter Brennan), and a bold, sexually-charged heroine (Lauren Bacall, in her screen debut). A few scenes even recur in the director's other films, such as the classic, post-kiss line, "It's even better when you help." Jules Furthman and William Faulkner loosely adapted the screenplay from an Ernest Hemingway novel; though the setting of To Have is the Caribbean, the characters and Bogart's unselfish transformation is clearly reminiscent of 1942's Casablanca. Hawks would exploit the tremendous chemistry between Bogart and Bacall again in his next film, 1946's The Big Sleep; the two stars married in the interim.
