Charlie Hunnam is being lined up to star in American Drug Lord.

The Sons of Anarchy star is reportedly set to play cartel leader Edgar Valdez in the movie, according to Deadline.

American Drug Lord is based on the 2011 Rolling Stone article of the same name by Vanessa Grigoriadis and Mary Cuddehe and centres on Valdez, who became the first US citizen to lead his own drug cartel.

Jason Hall (American Sniper) is writing the script, with Sarah Esberg of Plan B executive producing.

Hunnam will also play the leading role in Guy Ritchie's upcoming epic Knights Of The Round Table: King Arthur.
