 Some character names in this movie are clearly alluding to famous  (film) people of the past, such as Dietrich, Marlene (qv),  Lubitsch, Ernst (qv), Emil Jannings and painter Oskar Kokoschka.  At the same time the female lead Sattes, Ingrid (qv) looks very  much like the young Bergman, Ingrid (qv) while the male lead  Ulli, Pascal (qv) is reminiscent of Delon, Alain (qv).
