Colin Farrell and Michelle Dockery are ready to mix it up with the "Toff Guys."

They are joining the star-studded cast of Guy Ritchie's upcoming crime drama, which also includes Matthew McConaughey, Hugh Grant, and Henry Golding. "Downton Abbey's" Dockery is replacing Kate Beckinsale.

The movie is reminiscent of Ritchie's earlier gangster movies like "Lock, Stock and Two Smoking Barrels” and “Snatch.”

McConaughey plays a businessman who has built a weed empire and now wants out. Dockery is the man’s wife, while "Crazy Rich Asians" star Golding is a Vietnamese gangster. Grant is a photographer who snaps scandalous photos and uses them to blackmail McConaughey. Farrell will play an MMA fighting trainer.

Farrell can currently be seen in "Widows" and next stars in the live-action remake of "Dumbo." Dockery is currently shooting the "Downton Abbey" movie.
