Continuity mistake: About half way through the movie, the three main characters are in a loft. When the Asian girl grabs the postal worker's jacket, a cassette tape falls out of his pocket. As the girl bends down to pick up the tape, the camera shows here reaching with one hand, and then the camera switches to a close-up of her picking up the tape with the opposite hand.
Continuity mistake: Near the beginning of the film the two hitmen drive up to the station (where they are about to kill Nadia) in a very muddy black car. After they have made their getaway they are next seen at the scrapyard disposing of the same very clean black car.
