"The Omen" has been inducing nightmares since its 1976 release. 

With the power to disturb even jaded fans of the scary-movie genre, "The Omen" has been inducing nightmares since its 1976 release. This is probably due to its excellent lead, a young actor who convincingly and creepily inhabits the role of the satanic kid. Gregory Peck plays Robert Thorn, a recent father who secretly swaps his diseased newborn for an orphaned infant in order to protect his wife's mental well-being. Over time, Robert realizes the young boy may in fact be the Antichrist. With horror movie elements that inspired such films as "Orphan" and "The Ring," "The Omen" was a major technical and even musical advancement for the genre — composer Jerry Goldsmith won an Academy Award for the score.
