<P> Keith and Robert travel to Rome to investigate Damien's birth . A fire destroyed the hospital records and the maternity and nursery wards five years earlier; most of the staff on duty died in the fire . Robert and Keith trace Father Spiletto to St. Benedict's Abbey in Subiaco, where he is recuperating from his injuries . Stricken mute, blind in his right eye and paralyzed in his right arm, Spiletto writes the name of an ancient Etruscan cemetery in Cerveteri, where Damien's biological mother is buried . Robert and Keith find a jackal carcass in the grave, and in the child's grave next to it, a child's skeleton with a shattered skull . These are Damien's unnatural "mother" and the remains of the Thorns' own child, murdered at birth so that Damien could take his place . Keith reiterates Father Brennan's belief that Damien is the Antichrist, whose coming is being supported by a conspiracy of Satanists . A pack of wild Rottweiler dogs, similar to ones seen near the Thorn's mansion, drive Robert and Keith out of the cemetery . </P> <P> Back in London, Mrs. Baylock persuades a nurse to allow her access to Katherine, who is heavily sedated and under police protection . Once inside the room, Mrs. Baylock pushes Katherine out of the window, and Katherine lands on the roof of an ambulance, killing her . Robert and Keith travel to Israel to find Carl Bugenhagen (Leo McKern), an archaeologist and expert on the Antichrist . Bugenhagen explains that if Damien is the Antichrist he will possess a birthmark in the shape of three sixes, under his hair if nowhere else . Robert learns that the only way to kill the Antichrist is with seven mystical daggers from Megiddo . Appalled by the idea of murdering a child, Robert discards the daggers . When Keith tries to retrieve them, he is decapitated by a sheet of window glass sliding off a truck, matching the shadow across his neck which had presaged his death . </P> <P> Returning home, Robert examines Damien for the birthmark, finding it on the child's scalp . Mrs. Baylock attacks him and, in the ensuing struggle, Robert kills her . He loads Damien and the daggers into a car and drives to the nearest church . Due to his erratic driving, he is followed by the police, who arrive as he is dragging the screaming child to the altar . An officer orders him to raise his hands and stand away . Robert raises the first dagger and the officer fires his gun . The double funeral of Katherine and Robert is attended by the President of the United States, who now has custody of a smiling Damien . Just before the credits roll, Revelation 13: 18 Appears "Here is wisdom, let him that hath understanding, count the number of the beast, for it is the number of a man and his number is 666 ." </P> <Ul> <Li> Gregory Peck as Robert Thorn </Li> <Li> Lee Remick as Katherine Thorn </Li> <Li> David Warner as Keith Jennings </Li> <Li> Billie Whitelaw as Mrs. Baylock </Li> <Li> Harvey Spencer Stephens as Damien Thorn </Li> <Li> Patrick Troughton as Father Brennan </Li> <Li> Martin Benson as Father Spiletto </Li> <Li> Leo McKern as Carl Bugenhagen (uncredited) </Li> <Li> Robert Rietti as Monk </Li> <Li> Tommy Duggan as Priest </Li> <Li> John Stride as The Psychiatrist </Li> <Li> Anthony Nicholls as Dr. Becker </Li> <Li> Holly Palance as Nanny </Li> <Li> Roy Boyd as Reporter </Li> <Li> Freda Dowie as Nun </Li> <Li> Sheila Raynor as Mrs. Horton </Li> <Li> Robert MacLeod as Horton </Li> <Li> Bruce Boa as Thorn's Aide 1 </Li> <Li> Don Fellows as Thorn's Aide 2 </Li> <Li> Patrick McAlinney as Photographer </Li> <Li> Betty McDowall as American Secretary </Li> <Li> Nicholas Campbell as Marine </Li> <Li> Ronald Leigh - Hunt as Gentleman at Rugby </Li> </Ul>
