Matthew McConaughey's signed up for Toff Guys, Guy Ritchie's return to British gangster films alongside Crazy Rich Asians' Henry Golding and Kate Beckinsale.

Variety reports that Ritchie will direct and produce from a script cowritten by himself and Marn Davies and Ivan Atkinson. Davies and Atkinson are first-time writers, but they've worked with Ritchie before - Davies was a policeman in Sherlock Holmes, while Atkinson was Ritchie's assistant on A Game of Shadows and The Man From UNCLE.

The plot will follow a British drug lord who's selling his weed empire to some folksy Oklahoma billionaires. Really, it should've been called The Muswell Hillbillies, but it's probably a bit late to change now.

That's most likely where McConaughey comes in. Other than that, all we've got to go on is this tiny gobbet from Miramax's CEO Bill Block: "McConaughey as the inside outsider with Henry and Kate will make for a thrilling Guy Ritchie ride."

Guy Ritchie's not done a Maximum Guy Ritchie Film - shooters, geezers, drugs, that sort of thing - for some time, and following the widespread shrugging which met the David Beckham-cameoing King Arthur: Legend of the Sword, Toff Guy will return to the kind of crime comedy he minted in Lock, Stock and Snatch.
