Directed by: Martin Scorsese

Deliberate mistake: In all the shoot-outs, the bullets that hit the cars spark, which bullets do not do, and leave no hole, dent, or even a small scratch. They do, however, break the glass.
Suggested correction: This isn't correct. In the big shootout towards the end, gunshots leave holes in car doors and break car windows from both sides of the fight.
Continuity mistake: In the scene after Queenan dies, when Sullivan picks up his phone to contact Costigan, he presses the "talk" button and a smudge of blood is left. In subsequent shots, there's no trace of blood on the "talk" button. (01:49:45)
Colin Sullivan: I'm going to need the identity of your undercovers.
Dignam: Blow me, all right? But not literally, though. Unfortunately, there's no promotion involved for you.
Trivia: The title track to the movie, which plays at the menu and twice in the movie, is "I'm Shipping Up to Boston", a hit song by the Dropkick Murphys. The Dropkicks are a Boston-based Irish band, fitting for a movie about Irish mobsters in Boston. The song is also the entrance music for Red Sox closer Jonathon Papelbon.
