A Mezuzah is a small wooden box that is attatched to every single doorway except the bathroom. It contains a small rolled parchment that declares the belief in one God. Meant to be touched upon going through the doorway, it is a tradition that is considered a part of Jewish law. It is attatched about two thirds of the way up from the floor and is touched by any Jewish person entering or exiting the room.
It is also tradition to remove it while moving so it cannot be treated with disrespect by another owner
As many of the scenes contain entering and exiting doors, any actor playing a Jewish character should be aware of this tradition.
During the ending scene of leaving Anatevka, it is also important to remember to remove it from the door before leaving.
