No sex/nudity, just a few minor references (that sort of hint at sexual material)

Very mild violence but still very disturbing. There are intense scenes that involve children. Most violence is implied and not fully seen. Theres a great deal of obvious murderous (or aleast harmful) intent

a couple of minor swear words, mainly british cursing

A girl who says she is 14 smokes in several scenes.

If released theatrically today, it would have earned a PG-13 rating for underage smoking, mild language, and thematic imageries of child abuse. One of the disturbing British films from the 1960s.

A young boy pretends to have hung himself in order to scare an old woman.
