Sons of Anarchy star Charlie Hunnam has joined American Drug Lord, about cartel leader Edgar Valdez, EW has confirmed.

As first reported by Deadline, Legendary acquired the original 2011 Rolling Stone article about Valdez a.k.a. La Barbie.

The story follows Valdez’s journey from a high school football player to a prominent cartel leader in Mexico. After making $130 million in one year, he became a brutal force, often allegedly filming executions of his rivals and sharing them on the Internet. As the cartels turned on one another, “Valdez’s life became a struggle to stay alive.”

American Sniper‘s Jason Hall will pen the script, while Hunnam will produce along with Legendary and Plan B’s Dede Gardner and Jeremy Kleiner. Sarah Esberg of Plan B will executive produce.
