Action in the North Atlantic, also known as Heroes Without Uniforms, is a 1943 American black-and-white war film from Warner Bros. Pictures, produced by Jerry Wald, directed by Lloyd Bacon, that stars Humphrey Bogart and Raymond Massey as officers in the U.S. Merchant Marine during World War II. Typical of other films in the era, Action in the North Atlantic was created as a morale-boosting film during this world war and a film that told the story of unsung heroes. As noted by film critic Bosley Crowther, "... it's a good thing to have a picture which waves the flag for the merchant marine. Those boys are going through hell-and-high-water, as 'Action in the North Atlantic' shows."
