Towards the end of the movie, both before and directly after shooting Oak, Tellis is seen armed with a 1911 style pistol. In both instances, the hammer is down. Prior to shooting Oak, this would mean the the weapon is not capable of being fired. Immediately after shooting Oak, the hammer would automatically be in the cocked position.
Nick Tellis breaks open the window of the car to get in even though it is clear that the doors are unlocked.
When Lt. Henry Oak is first seen, his jacket is off, revealing his shoulder holster rig. He is carrying a .357 magnum revolver, but the holster rig is made for a semiautomatic. The strap on the side opposite the pistol contains a case for a semiautomatic magazine.
The word "SENSITIVITY" is misspelled on the tape-recorder in the last scene of the movie.
When Calvess shoots himself, he aims the gun above his head. The bullet would have missed him completely.
Towards the end of the movie, Jason Patric breaks open the car window and, when he opens the door, the legs of several crewmembers are visible through the door's rearview mirror.
