Back in 2014, Clint Eastwood and Bradley Cooper dropped off their war-drama American Sniper. The duo will return, this time with Eastwood also starring, for a new film based on a true story. Entitled The Mule, Eastwood's latest drama draws influence from the story of  World War II veteran Leo Sharp. Sharp was the oldest known drug mule, moving cocaine for the Sinaloa Cartel until his arrest in 2011 at the age of 87.

According to VarietyEastwood will play a character named Earl Stone, the reimagined version of Sharp. Bradley Cooper will play a DEA agent, while Laurence Fishburne, Dianne Wiest, and Michael Pena round out the cast. A new trailer for The Mule was released this weekend, and it's filled with sorrow and introspection. 

“I was a terrible father and a terrible husband,” states Eastwood in the trailer. “Family’s the most important thing, don’t do what I did.” The regretful reflections haunt the entire trailer, which opens with a police officer approaching Eastwood's character. Already pulled over on the side of the road, and hurriedly preparing to hide cocaine in his trunk, Eastwood's Earl Stone is caught off guard when a drug dog picks something up. The Mule hits theaters on December 14.
