Plot hole: Roberta asks Jack to drive her car from the port to the casino to smuggle a transmitter through the checkposts. Since her links to the revolution were known to the authorities, and the chances that her car would be checked were much higher than with Jack's (which eventually also happened) it would have made much more sense if he had transported the transmitter in his own car.

Continuity mistake: In the first poker game Jack puts down his cigarette on an ashtray when the game is interrupted. The angle of the cigarette changes from one shot to the next (as if being put with the right or the left hand in different shots). (00:03:00)
