There is no such thing as breaking the first, second, or third wall because the word is derived from the assumption that a room has four walls. The "fourth wall" on stage is fictitious since it is where the audience is situated. There is also no such thing as shattering the fourth wall because there is no such thing as destroying evidence. The first wall is the front of the house. The third wall is the curtain that separates the backstage area from the audience. The fourth wall is the side of the theater where you are standing if you're in the audience. It's also called the screen wall because it often serves as the backdrop for a film or television show. The first wall contains the box office where people line up to pay money so the theater can buy food and drinks for its staff and guests. The second wall includes information signs about the play or movie, restrooms, and other amenities. The third wall is made of cloth and usually changes color to indicate which scene is happening inside the studio. The fourth wall is made of glass or plastic and allows people outside the booth to see what's going on inside. Sometimes actors will break the fourth wall by looking directly at the audience or waving at them.
