Children can be frightening at the best of times - they're loud, filthy and endlessly overdosed on sugar.
But in horror movies, they're even worse. So to mark the arrival of scary-kid creepfest Orphan to cinemas this Friday, we decided to look back at the weirdest kids on screen...
The Movie: The Omen (1976)
The Kid: Damien Thorn (Harvey Stephens)
Switched at birth with the stillborn child of American diplomat Robert Thorn, Damien is the Antichrist. No, not just a badly behaved little bastard, the son of Satan.
Tended by dodgy nanny Mrs Baylock (Billie Whitelaw), he creeps out everyone around him with his moody stare and annoying trike-riding.
The Scene They Probably Weren't Allowed To Watch: After Damien knocks his mother down the stairs, equally evil Mrs Baylock kills her with a truly fatal fall - chucking her out of her hospital room.
Next: The Ring
