Cosa Nostra, Arch Enemy of the FBI

Released theatrically in Europe, Cosa Nostra, Arch Enemy of the FBI originated as "The Executioner", a two-part episode of the weekly TV series The FBI. The series' usual stars Efrem Zimbalist Jr., Philip Abbott and Stephen Brooks are joined on this occasion by guest artists Walter Pidgeon, Celeste Holm, Telly Savalas and Susan Strasberg-and, way down on the cast list, Robert Duvall. The story concerns double-crosses within the inner circles of La Cosa Nostra. (allrovi.com)
