Revealing mistakes: As Brossard is about to place the body of the Jewish assassin into the car, he lifts the dead man's arms into the air in order to sit the body up. As he lets go of the arms, they do not immediately drop as they would for a dead man. Instead, they hesitate, then slowly drop to the ground.
Continuity: When Brossad kills the assassin, he removes the assassin's passport and places it in his right pants pocket. He removes the passport from his left pants pocket while he is sitting in the car at the abbey.
Continuity: When the statement is shown being typed, the typist underlines the name Pierre Brossard except for the P. When it is shown completed, the name is underlined completely.
