The Writer's Almanac with Garrison Keillor | If I Gave Up by Kelly-Anne Riess: "The film To Have and Have Not had its premiere on this day in 1944. It was based on the novel To Have and Have Not by Ernest Hemingway, which was a hard novel for Hemingway to write, and took him about four years. He had been accused of being politically apathetic, so in this novel he tried to engage with the politics of Cuba and Key West, but the result was generally panned by critics. Philip Rahv of the Partisan Review summed it up: “In transcending his political indifference, he has not, however, at the same time transcended his political ignorance.” Hemingway published the novel in 1937, and in 1939, he sold the film, radio, and television rights for $10,000."
Good stuff about Faulkner and the screenplay at the link.
