Henry Cavill is in his Inglourious Basterds era with his new Guy Ritchie action-comedy The Ministry of Ungentlemanly Warfare.

In the first trailer that debuted Tuesday, the former Superman actor, 40, leads a “secret combat unit, composed of a motley crew of rogues and mavericks,” according to a synopsis, that “goes on a daring mission against the Nazis using entirely unconventional and utterly ‘ungentlemanly’ fighting techniques.”

According to a press release, Ministry of Ungentlemanly Warfare is based on true event from recently declassified files of the British War Department. It’s adapted from the book The Ministry of Ungentlemanly Warfare: How Churchill’s Secret Warriors Set Europe Ablaze and Gave Birth to Modern Black Ops by Damien Lewis.

The operation was the “first-ever special forces organization formed during World War II by U.K. Prime Minister Winston Churchill and a small group of military officials, including [James Bond] author Ian Fleming.”

“Ultimately their audacious approach changed the course of the war and laid the foundation for the British SAS and modern Black Ops warfare,” the synopsis reads.

Ritchie, known for The Covenant, Sherlock Holmes and The Gentlemen, directed Ministry of Ungentlemanly Warfare, which features in its cast: Ambulance actress Eiza González, Reacher star Alan Ritchson, Magic Mike actor Alex Pettyfer, After actor Hero Fiennes Tiffin, Henry Golding, Cary Elwes, Babs Olusamokun, Henrique Zaga and Til Schweiger.

Cavill, who next stars in the spy movie Argylle, wrote on Instagram in April about completing work on Ungentlemanly Warfare.

“It’s rare to come across a team so driven, dedicated and committed to the storytelling,” he wrote at the time. “That drive and dedication is only intensified by having a leader such as Guy Ritchie. His ability to weave story and create character might be second to none, and he wields it like it were magic.”

“Those ingredients — skill, drive, and exceptional talent at the top — are only three of the ingredients needed for an experience that will last forever in memory. The fourth is happiness,” continued Cavill. “Guy creates happiness on his set, it’s a joyful place to be, full of laughter and japes and jests. The crew and cast’s approach and personality is key in this. Everyone, without fail, was able to enjoy themselves while also working hard and being exceptional.”

Cavill called costar Ritchson, 41, “the man mountain with a heart of gold,” who has “wisdom and talent that can sweep you off your feet.” About Pettyfer, 33, Cavill said he is “the lover, the laugher, the warmth of a big smile and a jaw line that would challenge the Turkish mountains.”

Golding, 36, has “a snap quick acting reaction time” and is “handsome beyond belief and always a man I was happy to see,” he added.

“And the last (but not the least) of my immediate team of misfits, Hero Fiennes Tiffin – a mega star in the making. I know a lot of you know him already, but my oh my he’s going to have a magnificent career,” Cavill added of the 26-year-old actor.
