Henry Cavill assembles 'The Ministry Of Ungentlemanly Warfare' in new trailer

Guy Ritchie's back with yet another crack team of hardboiled specialists and crooked characters to get the job done their way. To pull one over on some dodgy geezers, inevitably finding themselves sharing a tumble down the sink after copping a flower pot (Google it).

But this one's a little different, set during World War II and supposedly inspired by true events — based on declassified files of the British War Department.

Directed and co-written by Ritchie, the dramatically titled The Ministry Of Ungentlemanly Warfare has a brand new trailer that introduces you swiftly to such a league of extraordinary rogues, led by Henry Cavill and Cary Elwes. Eiza González, Alan Ritchson, Alex Pettyfer, Hero Fiennes Tiffin, Babs Olusamokun, Henrique Zaga, Til Schweiger, and Henry Golding also star.

The film apparently tells the tale of a top secret combat unit formed by Winston Churchill alongside some military folks and a certain Bond author Ian Fleming, sent on a mission to fight the Nazis by unconventional means, and preceding the British SAS and Black Ops warfare. Sounds like a lot, but if you're here for a history lesson, maybe grain of salt?

The Ministry Of Ungentlemanly Warfare hit cinemas April 19.
