 The films technical advisor was Thomas B. Duffy (qv), a retired  Massachusetts State Police major who worked out of Boston for nearly  thirty years and specialized in organized crime. He was particularly  involved in the case against notorious South Boston gangster Whitey  Bulger, whom Jack Nicholson (qv)s Frank Costello is partly based  on. Duffy appears as the Governor who delivers a speech to the  graduating police cadets.
