Played by: Mark Wahlberg
In The Departed, Mark Wahlberg played the type of hot-headed Irish cop that we just couldn’t stand. He was brash and ill-mannered, with the mouth of a disgruntled high school jock. But as Capt. Queenan’s right-hand man, Dignam also had the authority to act like the biggest tool imaginable and get away with it. This part called for someone who could get under our skin in a hurry, and it turns out that Mark Wahlberg was the man for the job. And when Dignam’s big reveal came at the end, it just added to his overall scumbaggery.
