A bus from the children's ward of a mental hospital crashes in the snow, killing everyone on board except for five little psycho buggers. The children (including a very young Leif Garrett) head towards a house in the hills, where they're taken in by a group of adults who think that they seem like normal enough kids. They couldn't be more wrong, though, as the crazy quintet sets up a series of grisly (yet admirably planned and executed) ambushes -- including the ol' piranha-in-the-bathtub gag.
14. Wake Wood (2011)
From the legendary Hammer Film Productions comes this tense and surprisingly grisly killer kid flick in the tradition of Pet Sematary, as a grieving couple is granted the chance to spend three days with their risen-from-the-grave daughter.
Fresh off of his stint in the family-friendly Home Alone movies, Macaulay Culkin opted to star as Henry, the pint-sized sociopath in the R-rated The Good Son, a guilty pleasure popcorn movie that affords us the opportunity to hear the 12-year-old use the "F" word (at last!). In the film, Henry's cousin Mark (Elijah Woods) comes to stay with him but soon discovers that this son is only "good" at murder and mayhem. The climax, in which Henry's mother must choose between the two boys, is a contrived thing of beauty.
12. The Omen (1976)
This prototypical killer child movie finds an American diplomat and his wife taking in a child who turns out to be the son of Satan. Deadly "accidents" seem to follow the kid around, as do fanatical nannies who tend to toss themselves off of rooftops. A chilling entry in the Satan-centric films of the late '60s and '70s, The Omen single-handedly ensured that no child would ever again be named Damien.
11. Whisper (2007)
This smartly crafted supernatural thriller plays like Ransom meets The Omen, as a quartet of ne'er-do-wells (including Lost's Josh Holloway) kidnap a wealthy family's son, only to realize that they've basically captured Damien. The eerily composed tyke has a talent for getting inside people's heads and making them want to kill.
This highly entertaining killer kid flick, shot in a POV ("home movie") style, tells the story of a husband and wife who, despite their efforts, end up with a couple of evil, evil kids.
9. Citadel (2012)
Sort of like Them with a supernatural element, this hypnotic urban fairy tale from Ireland features hoodied otherworldly kids tormenting an agoraphobic father trying desperately to protect his baby daughter.
A demented Shirley Temple-type named Rhoda cold-bloodedly kills anyone who prevents her from getting what she wants in this black-and-white classic. I'm not sure how seriously this movie was taken in its day, but it's hilariously campy fun now -- with the theatrical overacting and the chess match between Rhoda and the family's caretaker, LeRoy, who sees her for what she is and tells her that they have special pink electric chairs for little girls like her. The tacked-on ending -- in which Rhoda experiences biblical retribution -- is the icing on the cake.
This mix of Village of the Damned and Devil Times Five plays on the astrology craze of the '70s, as three children are born in the same town on the same night under a particularly odd alignment of stars...or whatever accounts for astrological readings. A decade later, as their 10th birthday approaches, the three suddenly team up to kill as many people as possible -- shooting, stabbing, strangling and even running over victims in mild-mannered, sociopathic ways. While it doesn't necessarily make much sense, Bloody Birthday is quick-paced, fascinating and disturbing -- largely because it's so well done.
