is told in the characters’ native languages; Polish, Ukrainian, Yiddish, German, and working-class Polish dialect Balak bounce from character to character, and these linguistic differences raise walls between everyone. For instance, in the depths of the sewers, tension mounts among the group as it’s determined who will lead. Ignacy Chiger (Herbert Knaup) demands that he have a say in how to proceed, and another pipes up: “Listen to the professor who refuses to speak Yiddish! All your education didn’t buy you any sense.” Moments later, Socha, unable to understand the conversation, shouts, “Speak Polish, damn it!” Although they face a shared crisis, they still have differences that must be set aside for the sake of their survival. This element adds to the believability of the story, while also amping up the discord among the characters.
