Humphrey Bogart wasn't always the cynical Rick Blaine or the weary Sam Spade. In 1943, he took to the high seas in Action in the North Atlantic, a film that feels less like a polished Hollywood blockbuster and more like a sweaty, oil-stained tribute to the guys who actually kept the war effort afloat. If you're looking for a movie where the heroes wear grease instead of capes, this is it. It's gritty. It’s loud. It’s surprisingly honest for a movie produced in the middle of a global conflict.
Most people today overlook this flick when they talk about Bogie's "big" roles. That’s a mistake. While Casablanca gets the postcards and the catchy quotes, this movie captures a specific kind of blue-collar dread that most war movies ignore. It’s about the Merchant Marine—the sailors who didn’t get the glory of the Navy but took all the hits from German U-boats.
The Brutal Reality of the Merchant Marine
Back in the early 1940s, the Atlantic was basically a graveyard. German "Wolf Packs" were hunting Allied supply ships with terrifying efficiency. Action in the North Atlantic doesn't sugarcoat this. The opening sequence is a masterclass in tension. You’ve got the Northern Star, a tanker carrying high-octane gasoline, which is basically a floating bomb. When the torpedo hits, it isn't a clean explosion. It’s a chaotic, fiery nightmare.
The film was actually produced with the full cooperation of the U.S. Maritime Service. They wanted people to see what these sailors were going through. It served as a propaganda tool, sure, but the "human quality" of the writing—handled largely by John Howard Lawson—makes it feel authentic. Lawson was later blacklisted as one of the "Hollywood Ten," and you can see his interest in the working man all over the script. These aren't polished officers. They’re guys who want a drink, a sandwich, and a chance to get home.
Bogart, Raymond Massey, and a Different Kind of Hero
Humphrey Bogart plays Joe Rossi, the first mate. He’s the pragmatist. Opposite him is Raymond Massey as Captain Steve Jarvis. Massey brings a certain gravitas, a stiff-upper-lip quality that balances Bogart’s more reactive, "regular guy" energy.
Their relationship isn't built on flowery dialogue. It’s built on competence. There’s a scene early on after their ship is sunk where they’re stuck on a lifeboat. The German U-boat surfaces, and the crew of the submarine actually films the struggling survivors. It’s a cold, calculated move that reflects real reports from the era. Bogart’s face in these moments says more than a three-page monologue ever could. He looks tired. He looks angry.

The chemistry between the crew feels lived-in. You’ve got Alan Hale (the father of the "Skipper" from Gilligan's Island) providing some much-needed levity, but even the jokes feel heavy with the realization that they might be underwater in an hour.
Why the Special Effects Still Hold Up
Believe it or not, the effects in Action in the North Atlantic won an Academy Award nomination. In an era before CGI, they used massive miniatures and actual fire on water. When you see a ship burning in this movie, your brain registers the danger because the physics are real. The scale is impressive.
Director Lloyd Bacon and the legendary cinematographer Ted McCord used deep shadows and tight framing to make the ship feel both like a fortress and a cage. When the crew is under attack, the camera stays low, sticking with the men at the guns or the engineers in the boiler room. You feel the claustrophobia of the engine room when the depth charges start going off. It’s loud. It’s jarring. It makes modern digital explosions look like cartoons.
The "Propaganda" Label and Historical Accuracy

Is it still a great movie? Also yes.

Warner Bros. was leaning hard into the war effort, and this movie was part of that push. However, it avoids the "Superman" trope. The sailors are terrified. They make mistakes. They argue. There’s a subplot involving Rossi’s wife (played by Ruth Gordon) that explores the toll the war took on the families left behind. It’s not just about the shooting; it’s about the waiting.
The movie also pays a surprising amount of respect to the Soviet allies of the time. There’s a long sequence where the convoy finally reaches Murmansk, and the Russian citizens are shown as resilient, welcoming, and equally battle-worn. Given the Cold War that followed just a few years later, this part of the film is a fascinating time capsule of a moment when the geopolitical "good guys" list looked very different.
Common Misconceptions About the Film
Some people think Action in the North Atlantic is just a "B-movie" compared to The Caine Mutiny. That’s objectively wrong. It was a big-budget production for Warner Bros. and it was meant to be a flagship release.
Another common myth is that the movie ignores the reality of U-boat tactics. Actually, the film accurately depicts the "Wolf Pack" strategy—where multiple submarines would coordinate attacks on a single convoy. It also shows the transition from defenseless merchant ships to armed vessels. By the end of the movie, the sailors aren't just targets; they’re fighting back with 5-inch guns and Oerlikon cannons.
Technical Details for the Film Buffs
If you're watching this for the historical hardware, pay attention to the ship types. You’ll see the transition to the Liberty Ships, the mass-produced workhorses of the war. These ships were built fast and built cheap, but they were the backbone of the Allied victory.

Watching It Today: What to Look For
When you sit down to watch Action in the North Atlantic, don't just focus on the action beats. Look at the faces of the background extras. Many of them were actual merchant seamen or veterans. There is a weight to the way they handle the equipment that you just can't fake with actors who have never seen a deck winch.
Pay attention to the sound design, too. The contrast between the silence of the fog and the sudden, screaming roar of a Stuka dive bomber is genuinely unsettling. It uses silence as a weapon. You’re waiting for the "ping" of the sonar or the whistle of a falling bomb. It’s exhausting in the best way possible.
Actionable Insights for Your Next Movie Night
If you're planning to dive into this classic, here’s how to get the most out of it:
- Watch the 2020 film Greyhound first. Tom Hanks’ recent U-boat thriller is basically the high-tech cousin of this movie. Seeing how they tell the same story 80 years apart is a wild experience in how filmmaking has changed (and how it hasn't).
- Research the "Murmansk Run." Understanding how dangerous that specific shipping route was will give the final third of the movie a lot more stakes. It was arguably the most dangerous job in the entire war.
- Look for the "Blacklist" subtext. Knowing that the screenwriter, John Howard Lawson, was a committed activist adds a layer to the scenes where the crew discusses their rights and their role in the world.
- Check out the "Bogie" evolution. Watch this back-to-back with To Have and Have Not. You can see Bogart refining that "man who doesn't want to get involved but eventually has to" persona that made him a legend.
Action in the North Atlantic isn't just a relic. It's a loud, proud, and violent tribute to the merchant sailors who died by the thousands to keep the world fed and fueled. It’s a movie that respects the viewer enough to show that winning isn't easy, and it certainly isn't pretty. Turn off the lights, crank the volume, and prepare for a very long, very tense night at sea.
Next Steps for Enthusiasts:
To truly appreciate the era, look for the DVD or Blu-ray restoration which includes the "Warner Night at the Movies" feature. This recreates the 1943 theater experience with contemporary trailers, newsreels, and cartoons. For a deeper historical dive, read The Mathews Men by Brian Curtis, which provides a non-fiction account of the real-life merchant mariners who inspired the characters Joe Rossi and Captain Jarvis.
