As of 2017, this is the only film directed by Michael Haneke to have been screened in the official selection of the Cannes Film Festival without playing in the main competition. This is because that year's jury president, Patrice Chéreau, was part of the cast.
There's no music througout the entire film.
In nearly every Michael Haneke film, the main female character is called Anne Laurent or some variation. Isabelle Huppert made three films with Haneke (this, The Piano Teacher (2001), and Amour (2012)). This Is the only film in which she is named Anne Laurent.
