He’s been a boxer, a cop, porn star, rock star, soldier, football player, and private eye. So what’s next for Mark Wahlberg? Deadline.com reports that the onetime juvenile delinquent from Dorchester may star in “Deepwater Horizon,” a movie about the catastrophic 2010 explosion of the BP oil rig in the Gulf of Mexico. (Wahlberg would play the No. 2 manager on the doomed rig.) The script, written by Matthew Michael Carnahan, who also authored “World War Z,” is drawn from a New York Times article recounting the events that led to the explosion. Eleven people were killed and the blast resulted in the largest offshore oil spill in US history.
