Tony Zhou of Every Frame a Painting explains how chairs play an important detail in the film. Through a variety of examples, he not only shows how chairs are an “extension of the world,” but also tie in additional elements about the character. It can show whether a character is poor or wealthy, the character’s personality, or a physical representation of the character.
Zhou also points out how the right chair can add more to the scene to show the state of the character. He uses a scene from Godfather 2 where Fredo tries to sit up, but his chair won’t let him.
This is what great production design can get you, that one detail that pays off in unexpected ways. And it doesn’t have to be a chair, they’re just very common and pretty cheap. But the next time you have a scene and you ask the actors to sit, consider this: What do they sit on? And is there a way for that object to be something more?
