An undercover cop and a mole in the police attempt to identify each other while infiltrating an Irish gang in South Boston.
Jack Nicholson refused to wear a Boston Red Sox hat during filming, and instead wore his New York Yankees hat.
There was a cop leaving when I came in.
Madolyn: How did you know he was a cop?
Billy Costigan: Know, bad haircut, no dress sense, and, you know, a slight air of scumbag entitlement.
(at around 1h 30 mins) When Costello and Costigan are sitting at the table in the restaurant, discussing who the rat is, a handgun falls to the floor. Costello picks it up and points it at Costigan's face. You can hear him manually cock the hammer, but when the camera angle changes, the hammer is not cocked back.
The title doesn't appear on screen until nearly 20 minutes into the movie.
