This link has been sitting in my queue for months, but it’s still worth sharing. Tony Zhou looks at how character choice is framed as going left or right.

You see this technique in movies going back to the dawn of cinema, but no recent movie has used it as fully as Snowpiercer, in which the entire film moves on a linear track.

On the page, you’ll rarely call out “right” or “left.” But that sense of forcing characters to choose between two visual possibilities is a fundamental and frequently-useful paradigm.
