A horror classic. I absolutely love this film which is the story of an American ambassador and his wife who find out their adopted son is the antichrist. Don't you just hate when that happens! Director Richard Donner [The Goonies, Superman] lets the tension build slowly throughout the film until it reaches a frenzy in the final scene. Nicely done. The screenplay is intelligent, well-written and doesn't descend into the kind of religious mumbo jumbo many films of this type do. We discover what's going on the same time the characters in the movie do and this serves The Omen very well.
The cast includes screen legend Gregory Peck [Cape Fear, The Boys From Brazil] as Robert Thorn and Lee Remick [Anatomy of a Murder, Days of Wine and Roses] as Katharine Thorn. They are great together as the terrorized couple who gradually discover that their precious baby boy is not exactly that precious. I also enjoyed veteran character actor David Warner's performance [Titanic, Avatar] as Keith Jennings, Robert's companion in discovering Damien Thorn's true identity. Also a shout out to Harvey Stephens who plays little Damien. His look at the end of the film is haunting, disturbing and priceless.
The soundtrack is effective as well. I like to call it "Satan's Show Choir." It's what Glee would sound like if Lucifer were their teacher. It really adds a lot to the emotional feel of the movie. If by some chance you missed this one, put it on your list immediately. I wish all horrors films were made this well. It's one of the best of the 1970's.
