20 BDSM Movies More Provocative Than Fifty Shades Of Grey

2. The Piano Teacher

Austrian director Michael Haneke has established himself over the years as something of a master of transgressive cinema, forcing the audience to confront their own voyeuristic tendencies when they pay to watch movies depicting violence, be it physical or emotional. With The Piano Teacher Haneke turns his attention towards the outwardly respectable professional who harbours desires she'd much rather weren't made public. From self-mutilation to voyeurism, the eponymous teacher eventually develops a mutual obsession with a young man whom she takes on as her student. The Piano Teacher marked yet another milestone in Haneke's superlative career and is a fascinating, richly detailed study of sado-masochism in the modern world.
