The Ministry of Ungentlemanly Warfare (2024) Review: An Underrated Gem

🎖️ This review is part of our look at Alan Ritchson’s rise as an action star — see how his supporting turn here stacks up against Reacher and War Machine.

When The Ministry of Ungentlemanly Warfare hit theaters in April 2024, it landed with barely a ripple — a few thousand screens, a soft opening weekend, and a reported $60 million budget against roughly $29 million in domestic box office. That should have been the end of the story. Instead, the film quietly became one of the best-reviewed studio action movies of the year (73% from critics, a genuinely rare 94% from audiences on Rotten Tomatoes) and found a real second life once it started streaming. Having finally caught up with it myself, I can say the audience score is the one that got it right. This is a sharp, confident, unexpectedly funny war movie that deserved a completely different release.

The way to actually see Ritchie's widescreen framing and Alistair Slater's cinematography properly.

Guy Ritchie is directing at the top of his game here, and it shows in every frame — this isn’t the scattershot Ritchie of his weaker studio work, it’s the guy who made Lock, Stock and Snatch, applying that same lean, propulsive, character-first instinct to a true story instead of a heist. For a dad who grew up on Ritchie’s early crime films and has watched some of his more recent output miss, this is the one that proves he still has it when the material is right.

That audience-versus-critics gap is worth sitting with for a second, because it tells you exactly who this movie was actually made for — and why the marketing apparently never found them.

Narrative Architecture: A Heist Movie Wearing a War Movie’s Uniform

The emotional engine here isn’t grief or trauma, which is unusual for a modern war film — it’s a bunch of misfit specialists finally being told to stop following the rules that got them sidelined. Winston Churchill (Rory Kinnear), fed up with the regular Army’s caution, greenlights an off-the-books unit to go do the things a proper military campaign can’t officially sanction.

The plot itself is a clean heist structure dressed in fatigues: Gus March-Phillipps (Henry Cavill) assembles a small crew of specialists — a demolitions expert, a knife specialist, a sharpshooter — and infiltrates the neutral Spanish port of Fernando Po to sink and steal a fleet of ships supplying German U-boats, before the operation spirals into a much louder finale than the plan called for. It moves fast, it doesn’t over-explain itself, and it trusts the audience to keep up.

For a dad who’s spent a career being the guy who follows the process, there’s something genuinely satisfying about watching a crew of competent, slightly unhinged specialists get permission to stop asking for it. Gus isn’t reckless — he’s precise. He’s just precise about things the regular chain of command would never sign off on, and the film’s whole pitch is watching what happens when that precision finally gets a green light.

That contrast is the whole film’s engine, and it’s why the casting works so well: Cavill plays restraint as a weapon, Ritchson plays restraint as something he’s visibly working to hold onto. Put them in the same unit and every scene they share has real tension in it before a single shot is fired.

Guy Ritchie’s Craft: Turning a Forgotten Raid Into Genuine Style

What’s technically remarkable here is how confidently Ritchie blends tones that shouldn’t work together. This is, on paper, a film about a real WWII commando raid — and it’s also frequently very funny, in the same dry, quotable register as his crime films. That’s a hard needle to thread, and a lesser director would either play it straight and lose the personality, or lean into the comedy and undercut the real violence. Ritchie does neither. The jokes land because the characters are sharp, not because the film winks at the audience about the stakes.

Three specific choices make it work:

1. The pacing never idles. At 120 minutes, there’s no bloated second act — the film gets the crew assembled and into motion fast, then trusts the raid itself to carry the back half.
2. The violence stays honest. When it’s brutal, it’s genuinely brutal, not stylized into something bloodless. That grounds the funnier stretches instead of undercutting them.
3. Chris Benstead’s score does real narrative work. A Spaghetti-western-guitar-meets-jazz-trio sound that has no business working in a WWII film, and somehow makes every scene feel like it knows exactly what kind of movie it is. Benstead won the IFMCA award for it, and it’s earned.

The real, far bloodier history the film is based on — Churchill's actual secret warriors, in full.

The history underneath all of this is the part that stayed with me longest. Operation Postmaster was a real, largely forgotten 1942 raid, and the unit it depicts — the Small Scale Raiding Force — is a genuine ancestor of the modern special forces model. Anders Lassen wasn’t a screenwriter’s invention either; he really did go on to earn Britain’s Victoria Cross before the war ended. Knowing that while you watch changes how the third act lands. This isn’t just a fun action movie borrowing WWII as set dressing — it’s a fun action movie that happens to be telling you something true.

The actual raid is a genuinely wild piece of history worth knowing going in. Fernando Po was a neutral Spanish colonial port, which meant the Allied ships supplying German U-boats there were technically untouchable — you can’t stage a naval assault on a neutral country’s harbor without triggering a diplomatic catastrophe. Churchill’s solution was exactly the kind of off-the-books thinking the film dramatizes: send in a deniable, irregular unit to sink and tow away the ships under cover of night, so quietly that nobody could prove it was a military operation at all. It worked. Not one shot was fired at the actual historical raid, and the Small Scale Raiding Force’s success helped convince a skeptical War Office that irregular warfare was worth funding — a direct lineage to the SAS and the modern special forces model most of us only know from movies. Ritchie’s version amps up the noise for the third act, understandably, but the core premise — audacity and deniability beating brute force — is straight out of the real record.

The Home Cinema Case: Why This One Rewards a Real Setup

Most people are going to meet this film the way it actually found its audience — at home, after a bad theatrical run buried it everywhere else. That’s genuinely fine here, because the things that make it work translate well to a couch:

• The sound design carries a lot of the tension. Benstead’s score and the raid’s practical gunfire mixing deserve better than laptop speakers — this is a real-soundbar-or-better watch.
• The widescreen framing still reads on a big TV. Alistair Slater’s cinematography leans into wide, uncluttered compositions that hold up even without a theater screen.
• Dad Alert: This is not a family movie night pick. Queue it up solo or with a partner after the kids are down — the violence and language are the real thing, not a PG-13 approximation of it.

The budget-friendly disc option if 4K isn't a priority.

Want to watch it tonight? Prime Video’s 30-day free trial is worth grabbing for the rest of your watchlist regardless — catalogues change, so check what’s currently streaming before you commit an evening to any one title.

Is The Ministry of Ungentlemanly Warfare worth watching?

Yes — 4/5. It is a stylish, well-cast, genuinely funny-and-brutal war movie that got buried by a bad release strategy, not by quality. If you liked any of Guy Ritchie’s crime films, this is that same energy applied to a true WWII story.

Is The Ministry of Ungentlemanly Warfare based on a true story?

Yes, loosely. It dramatizes Operation Postmaster, a real 1942 raid by Britain’s Special Operations Executive on Axis supply ships docked in the neutral port of Fernando Po, considered one of the first missions of what would become the modern special forces model. The film is based on Damien Lewis’s nonfiction book of the same name.

Who plays who in The Ministry of Ungentlemanly Warfare?

Henry Cavill plays Gus March-Phillipps, the unit’s founder; Alan Ritchson plays Anders Lassen, a real Danish-born officer later awarded Britain’s Victoria Cross. Eiza Gonzalez, Alex Pettyfer, Henry Golding, Hero Fiennes-Tiffin, Cary Elwes, Til Schweiger, and Freddie Fox (as a young Ian Fleming) round out the cast.

Is The Ministry of Ungentlemanly Warfare suitable for kids?

No. It’s Rated R for sustained, graphic combat violence, strong language, and brief sexual content. Treat it as an after-the-kids-are-in-bed watch, not family movie night.

Where can I watch The Ministry of Ungentlemanly Warfare?

It’s available to rent or buy digitally, including on Prime Video, and has also streamed on Starz. It isn’t included with a base Prime membership, so check current availability before you commit an evening to it.
