Blooper

When woman is killed in her apartment, locket is under her, but in the next shot, it's clearly visible and not under her.

Early in the graveyard scene, as they are walking, the position of the actors changes between shots. In the side angle, Karl Malden has his left arm raised with his hand on James Franciscus' right shoulder, in the angle showing them from the front, Malden has his arm down and Franciscus is gripping his shoulder.

When Anna is escaping from the police, at the end of the chase, we first see her get away, and then policemen come and are confused, because they lost them. Car's parked are different between two shots and so is the traffic. In the first shot the street is empty, while in the second there's traffic.

Two men fight, one throws a stool at the other and he for some reason ends up on the different side of the room. Stool disappears.

It appears the barber shaves the right side of Giordano's face twice. However, part of the scene is shot in a large mirror, so it only *appears* the barber shaves the right side of his face twice.

When Carlo and Anna meet at the rooftop cafe for a drink, it appears to be late afternoon. A few moments later, a waiter replaces an ashtray and, when the camera goes back to the couple, it is almost totally night time.

During the fight scene at Braun's, James Franciscus, undubbed, can be heard saying, under his breath, an obscene equivalent of the phrase "Gonna "mess" you up!"
