Man staring at Trelkovsky in the movie theatre (uncredited)
Did you know?
Philippe Sarde (the composer) chose the glass harmonica after having seen Polanski, at the restaurant, mimicking with his finger the action of making the glass sing. There was only one person left in the world that could play this instrument, for which Mozart wrote a few pieces.
When Trelkovsky is unpacking as he moves into the apartment, a crew member is reflected in the small mirror adjacent to the kitchen sink. Two crew members are then reflected in the armoire's mirror as Trelkovsky opens it.
