 In the opening sequence with Tony Montana (Al Pacino (qv)) and the  immigration officers, Charles Durning (qv)s voice has clearly  been used to overdub an actor playing one of the officers. Another  of the officers is dubbed by Brian De Palma (qv) regular  Dennis Franz (qv). If you listen carefully, Al Pacino (qv) also  had to overdub his own voice at three or four different points in  the same scene.
