 Wolfgang Görtschacher (qv) teaches English literature at the  University of Salzburg. Christian Genzel (qv), who took some of  his classes, convinced him to play the small part of Iggy, the bar  owner. In the screenplay, Iggy plays poker with some friends, but  Görtschacher brought his set of dice and started to play with some  of the extras. Genzel liked their interaction so much that he asked  the crew to shoot the scene without telling the actors that the  camera was rolling.
