Humphrey Bogart is a hard-nosed fishing boat skipper who becomes involved helping locals thwart the Vichy-controlled government on Martinique while being hounded by Nazi sympathisers.

He’s helped by his alcoholic first mate, brilliantly played by Walter Brennan, and slinky lounge singer Lauren Bacall. This blistering drama shot the 19-year-old Bacall to superstardom.

It places her alongside her husband-to-be Bogart, then the biggest name in Hollywood, in a film based on a story by Ernest Hemingway, made into a script by William Faulkner and directed by Howard Hawks. Now that’s what you call pedigree.
