3 pieces in this section
The box opens and takes the film with it
A blue box and a blue key. What happens when they meet is the hinge of the whole structure, and the film declines to say what either one is.
Two keys, and neither fits anything ordinary
The blue key in the second half is not the blue key in the first. That is either the clue or the joke. Lynch's own clues decline to say which.
A studio meeting conducted entirely about coffee
The Castigliane brothers reject an espresso and, by doing so, cast a film. It is the clearest thing the movie says about how decisions actually get made.
