A deceptively quiet, disturbing chiller from director Robert Mulligan (To Kill A Mockingbird) and novelist/screenwriter Thomas Tryon. In 1930s rural Connecticut, young Niles (Chris Udvarnoky) tries to resist the evil influence of his twin Holland (Martin Udvarnoky), as terrible ‘accidents’ wrack the neighbourhood (climaxing in one of the nastiest shocks in cinema).
It has a big reveal an hour in (much copied recently), but there’s more creepiness to come, and you’re left with a lasting chill and a mystery which could be supernatural or psychopathic. The Udvarnokys, who never acted again, are up there with Danny Lloyd of The Shining as one-shot horror kids.
