The next Guy Ritchie film is gathering pace. Following his live-action remake of "Aladdin," due May 2019, the Brit director has a new project with Colin Farrell and Michelle Dockery of "Downton Abbey" joining Matthew McConaughey in crime drama "Toff Guys."

Colin Farrell is going from Steve McQueen's "Widows" and the March 2019 Disney remake of "Dumbo" to Guy Ritchie crime drama pic "Toff Guys" as a Mixed Martial Arts trainer named Coach, according to The Hollywood Reporter.

Matthew McConaughey is already involved as the film's lead, a marijuana mogul who is trying to get out of the business, with Michelle Dockery, best known for her Emmy-nominated performances as Lady Mary Crawley in "Downton Abbey," replacing Kate Beckinsale as the lead character's wife.

Also involved in known roles are Hugh Grant ("Four Weddings and a Funeral," Guy Ritchie's "The Man from UNCLE") as a photographer who tries to blackmail McConaughey's character, and English-Malaysian actor Henry Golding ("Crazy Rich Asians") as a Vietnamese gangster.

Guy Ritchie broke through at the turn of the millennium with crime comedies "Lock Stock and Two Smoking Barrels" and "Snatch," and "Toff Guys" is supposed to be in the same style and, as fans, cast and crew, and corporate execs will be hoping, of the same box office potential.

Those first two movies were all-round successes, "Lock, Stock," making $28m on a $1m budget and Brad Pitt starrer "Snatch" turning its $10m foundation into a $83m USD international box office grab.

The "Sherlock Holmes" franchise has proven Ritchie's biggest and most reliable vehicle, the 2009 and 2011 crime comedies netting $1bn between them.

Even so, 2015 comedy spy movie "The Man from UNCLE" and, particularly, 2017 fantasy "King Arthur: Legend of the Sword" did not fare as well, giving "Aladdin" and then "Toff Guys" the potential to represent a return to form.

As well as "Dumbo," in which he plays circus veteran and elephant whisperer Holt Farrier, Colin Farrell has Jessica Chastain action thriller "Eve" on his 2019 slate.

Michelle Dockery is part of the "Downton Abbey" cast working on a feature-length continuation of the hit historical British TV drama; in addition to three Emmy nominations for the episodic series, she received a fourth nod for her lead role in limited series Western "Godless."
