Haneke finds his match in Isabelle Huppert, who delivers an icy but quietly seething performance as Erika, a middle-aged piano professor at a Viennese conservatory who lives with her mother, in a claustrophobically codependent relationship.
Severely repressed, she satisfies her masochistic urges only voyeuristically until she meets Walter (Benoît Magimel), a young student whose desire for Erika leads to a destructive infatuation that upsets the careful equilibrium of her life.
A critical breakthrough for Haneke, The Piano Teacher — which won the Grand Prix as well as dual acting awards for its stars at Cannes — is a formalist masterwork that remains a shocking sensation.
