Michael Peña and Dianne Wiest have officially joined the cast of Clint Eastwood‘s upcoming film, The Mule.

Other members of the cast include Bradley Cooper, Laurence Fishburne, Alison Eastwood, Taissa Farmiga, and Ignacio Serricchio.

The film centers around an 90-year-old horticulturist and WWII veteran named Earl Stone (Eastwood, who is starring and directing). He is lonely, broke, and facing foreclosure on his business when he’s offered a job where all he needs to do is drive. Little does he know that he has become a courier for the Mexican drug cartel.

When Stone becomes exceptionally good at the job, he is given a handler to work with. It isn’t all bad deeds with no backlash, though. Soon, the DEA sniffs out the wrong-doings and starts searching for this new and mysterious drug mule. The ensuing pressure begins to prey upon Stone’s conscience, but it may be too late for Stone to turn back from the life of crime he began, especially with both the law and the cartel breathing down his neck.

Cooper plays the DEA agent assigned to find and stop Stone, while Wiest portrays the ex-wife of Stone. Her role in particular is said to be a heavy, deep, emotionally draining performance. Wiest is a two-time Oscar winner for her roles in Hannah and Her Sisters and Bullets Over Broadway.

Peña also ratchets up the intensity as an intimidating drug cartel enforcer, serving as contrast to his typical role as the comedic sidekick. Peña can next be seen in the upcoming film Ant-Man and the Wasp.

Filming began this past Monday in Augusta, Georgia.
