''The Omen'' is a horror film series that started with a 1976 film.

The films in the series are:

* ''Film/{{The Omen|1976}}'' (1976)
* ''Film/DamienOmenII'' (1978)
* ''Film/OmenIIITheFinalConflict'' (1981)
* ''Film/OmenIVTheAwakening'' (1991)
* ''Film/{{The Omen|2006}}'' (2006)

The movie followed a cycle of '[[EnfantTerrible demonic]] [[CreepyChild child]]' movies, such as ''Film/RosemarysBaby'' and ''Film/TheExorcist''.

After the first three films were novelized, two non-canon book sequels were written by Gordon [=McGill=] (''Omen IV: Armageddon 2000'' and ''Omen V: The Abomination'') chronicling the exploits of Damien's son and his attempts to cause the end of the world through interfering with the international peace process. There were a number of copycat films such as the Italian-made Kirk Douglas movie ''Film/{{Holocaust 2000}}''. The death scenes and causes of them also allegedly inspired the ''Film/FinalDestination'' film franchise.

In 2016, a TV series based on the films called ''Series/{{Damien}}'' premiered on A&E.

[[IThoughtItMeant Not to be confused with]] American heavy metal band Omen.

!! This movie series contains examples of:


* TheAntichrist: Damien.
* ArcWords: "Look at me Damien! It's all for you!"
** Also doubles as [[spoiler:FamousLastWords]].
* BirthmarkOfDestiny: Damien, of course, bears the MarkOfTheBeast (hidden conveniently beneath his hair).
* BitchInSheepsClothing: Damien's many secret protectors are often seemingly nice individuals. Damien is a debatable example as he never does anything overtly evil in the first film directly and it's left ambiguous of how aware he is of ''what'' he is.
* CassandraTruth: Anyone who brings up something being odd about Damien is usually dismissed, regardless of how rational they are. Then there's the people who flat out call him evil, his mother among them, and all are viewed as crazy. [[spoiler: Though subverted in that certain secret Satan worshipers are deliberately being dismissive.]]
* ChildrenAreInnocent: [[SubvertedTrope ... not.]]
* CreepyChild: Well, he's quite adorable for the son of Satan but he still does things that creep out other characters and of course the audience. Interestingly this trait is ramped up considerably in the 2006 version.
* DeathByPragmatism: Invoked by Satan and his followers. The moment anyone becomes aware of what Damien is, or comes close to revealing it unwittingly or not, they're as good as dead.
* DownerEnding: [[spoiler:Except the third movie, although even then, Damien does manage to cause a ''lot'' of pain and death before he's finally taken down.]]
* DrivenToSuicide: In the first film, the famous "It's all for you!" scene where a maid hangs herself. In the third film, an ambassador is spellbound to kill himself with a gun so Damien can take his place.
* EnfantTerrible: The plot of the first film. He's better behaved at the start of the second, until he learns of his call.
** Well outside of throwing a temper tantrum when he comes near a church, and knocking his mother off the stairs (which may or may not have been an accident) it's debatable on this in the first film.
** Delia in the fourth film is a much straighter example.
* GreaterScopeVillain: Satan himself. He is never shown, but his influence grooms Damien to become the ultimate evil as well as dissuade anybody that knows too much.
* {{Hellhound}}: Damien is guarded by a squadron of Rottweilers.
* HybridMonster: [[spoiler:Damien's real father is the Devil... and his mother was a ''jackal''.]]
* LonelyPianoPiece: Shows up here and there, particularly after [[spoiler:Cathy's death]].
* MarkOfTheBeast: Damien has a small birthmark [[spoiler:on his scalp]] resembling three sixes.
* NamesToRunAwayFromReallyFast: This film series forever stained the name, Damien, which was originally associated with a ''saint''.
* NumberOfTheBeast: Sixes surround this kid's existence, in fact. He was born on June 6th at 6am.
* NothingIsScarier: The build up to the deaths throughout the original trilogy were pretty intense, the deaths themselves were terrible ways to go for the most part but almost a relief when they come. The remake has elements of this too. It could be argued that [[http://www.youtube.com/watch?v=lwgSX7a9yDs this teaser]] for the remake is infinitely more terrifying than the movie itself.
* NunsAreSpooky: Like the one who tells Thorn that she can't give him any information about his child.
* OffingTheOffspring: The 'Bad Seed' variant. [[spoiler:It doesn't work]].
* OminousLatinChanting: "Ave Satani".
* ReligiousHorror: It's a given since the Antichrist is the main antagonist.
* RevealingCoverup: At times, the Satanic forces that try to protect Damien actually wind up helping to convince skeptics that he is, indeed, the Antichrist. Had all those mysterious deaths been a little ''less'' spectacular/creepy, Thorn and others might never have believed they were anything but accidents.
* RubeGoldbergHatesYourGuts: And they go off with not so much as a hitch since they are planned by ''The Devil''.
* SecretCircleOfSecrets: Nearly every other person around Damien seems to be a member of a [[ReligionOfEvil Satan-worshiping cult]] who are loyal to the death and do the dirty work of murdering those could threaten Damien when the accidents don't.
* ShootTheShaggyDog: The first two films end like this.
* SickbedSlaying: [[spoiler:Katherine Thorn]] in the first film and its remake. The way it's done is different in the remake, though.
* SugaryMalice: The babysitter.
* YouHaveOutlivedYourUsefulness: If Damien doesn't kill you for standing in his way, he'll kill you for this. Father Brennan warns Robert Thorn in the first film that this is his (Thorn's) fate once Damien is assured to inherit the Thorn family wealth.

[[folder:The [=NonCanon=] Novels]]
* BodyHorror/ DeathByChildbirth / FetusTerrible: How Damian's son is born.
* OmnicidalManiac: Unlike his father who intended to rule the Earth, Damian Jr. just wants to see it burn.
* StrongFamilyResemblance: Damian Thorn Jr. looks just like a younger version of his father. Not surprising, as Junior is heavily implied to be Damian's reincarnation. He's kept in hiding for this reason.
* TechnologyMarchesOn: The novel is set in the year 2000, and at one point the character needs to look up a piece of information. He does so by requesting the use of a hotel's sole computer, which is a giant monstrosity that is wheeled into his room by the hotel staff. He asks the staff if the book he is looking for in the computer's database, to which the staff member assures him that the computer holds every book. Later, while using the computer, the character makes queries to the computer which then draws logical conclusions based on the questions he asks it, something which no computer in any era is able to do. Perhaps the author didn't realize that even in the future computers can only organize information, it's still up to people to draw conclusions from that data.
* TwentyMinutesIntoTheFuture: The novels were written in the early 1980s, and set in the year 2000.
