Continuity mistake: In the scene where Corky first enters the Vet Clinic, and speaks to the "patients", the shot when he first speaks to the old man with the Bassett Hound, the dog is in the chair on the man's left, but in the next shot, the dog has moved to the right, and the man has shifted to the left side of the chair.
Continuity mistake: When Corky is dressed as the girl scout and is about to kiss the female agent/nurse, there is a side shot of them and they're leaning towards each other. Then there is a close-up of the female agent and she is puckering her lips. When it switches back to the side shot, she isn't puckering. This happens several times throughout the scene.
Continuity mistake: When Corky is chasing the cat at the start of the movie, he opens (breaks?) his fly trying to get the snake out of his pants. In the next shot, he is squatting facing the camera looking at the cat (who is at the bottom of the shot). It is obvious his fly is done up again, even though no attempt has been made to do up the fly.
Corky Romano: You know, I never thought I'd live to see the day that an FBI agent would be peddling smack.
Brick Davis: Don't act so surprised. J. Edgar Hoover use to wear a dress.
Corky: Just tell me why, Brick.
Brick: I don't know. I suppose it made him feel sexy.
Corky: Not Hoover, you.
Brick: I think it's time to get on with the meeting.
Corky: What meeting?
Brick: The meeting between your genitals and this knife.
