Critics have speculated that the film's Kafkaesque atmosphere must be in part a reflection of Polanski's own Jewish experiences within a predominantly anti-Semitic environment. Trelkovsky is viewed with suspicion by almost every other character simply because he has a foreign name. For example, when he tries to report a robbery to the French police he is treated sceptically and told that as a foreigner he should not make trouble. Both the director and the protagonist are outsiders who strive ineffectually for acceptance in what they see as a corrupt and mysterious world.
