Continuity mistake: After the hitman barges into Diamond's apartment and slugs him, Diamond collapses into a chair and both ends of his loose tie fall to the right. In the very next shot, the two ends of the tie are evenly spaced on either side of his shirt buttons.
Continuity mistake: The taxi Diamond follows has no markings on the side when it first pulls away. During the drive, it suddenly has both markings on the side and an advertising sign on the back. But when it stops, the cab again has no markings, and the sign has disappeared.
