Three cracking films and cracking soundtrack too by Jerry Goldsmith; elsewhere:-
The Omen (1976): He was born at 6am on the 6th day of the 6th month. The coming of Armageddon, the sign of the final confrontation between the forces of good and evil, as foretold in the Book of Revelations, will begin with the birth of the son of Satan - in human form.
The Omen II (1978): After the tragedy that befell his parents, Robert and Katherine Thorn, Damien is taken in by his caring Aunt and Uncle. However, Damien is growing and so too are his mysterious powers - it is time for Damien to find out what his destiny really is...
The Omen III (1981): Armageddon has come and the Evil One stands among us. His name is Damien Thorn and the power of evil is no longer in the hands of a child. The final and most terrifying chapter in the Omen Trilogy sees the fate of all mankind hanging in the balance, as the battle lines are drawn for the ultimate war between good and evil, for the Final Conflict.
