Former rapper and now actor Mark Wahlberg will star in an untitled film based on the life of Miami drug lord, Jon Roberts. Roberts was chronicled in the hit documentary, Cocaine Cowboys. The movie, which will be directed by Peter Berg, details Roberts time in Vietnam as a decorated soldier to his role in distributing billions of dollars worth of cocaine for the Medellin drug cartel while residing in Miami. Roberts, who eventually served ten years in prison for distributing drugs, is featured in DJ Khaleds video "I'm So Hood." The untitled movie is slated to go into production when the writer's strike ends.
