The Children's Hour (1961)

A child's gossip at a boarding school ruins the reputation of the two women who run the place together. This is a devastating movie, hindered only by a couple of performances: 1) the over-the-top "lead in the school play" style of the malicious little girl and 2) the barely-bothering-to-phone-it-in weirdness of James Garner.

Miriam Hopkins taking on the role of the flaky aunt (she played one of the teachers in the original version of the film) is a nice touch.
