Emma Thompson has transformed into the much feared Miss Trunchbull and looks unrecognisable as the official trailer for Roald Dahl's Matilda The Musical was released on Wednesday.
The actress, 63, looked worlds away from her usual appearance as fans got a first look at the terrifying headteacher in the teaser.
The family feature will be released at Christmas and Emma's Miss Trunchbull will be the stuff of nightmares over the festive season as she shows that no prisoners will be taken with her character.
