The Piano Teacher

Isabelle Huppert really played the piano in the film. She had studied piano for 12 years. As preparation for her role as a piano teacher, she resumed practicing a year before the film was started.

When Walter starts his piano audition; in the background, there are various teachers sitting in certain chairs. However in the following shot which is a medium-long shot of Kohut while Walter is performing; one of the female teachers is sitting in a different chair and a male teacher that was closest to Kohut is no longer sitting there but his belongings are on the chair. Then in the following shot after that, after Walter finishes his audition; the missing male teacher is back in his seat.

The R-rated edition from Kino makes a number of changes and omissions, removing the shots of the hardcore peep booth footage viewed by Huppert's character in the mall, as well as optically pixellating pornographic images on magazine covers in the sex shop. In addition, this version completely removes the following two sequences: -Huppert's cutting sequence in the bathtub -Magimel taking Huppert to the ground and humping her at the hockey rink. In the latter case, the film awkwardly fades out and in again in quick succession, to elide the missing footage.
