At one point in the movie Pollock, a biography of the artist Jackson Pollock, the artist receives a commission for his first huge painting. It is a canvas the size of an entire wall in a fairly large room. For days, Jackson sits in the room doing nothing. He paces, he sits in the corner, his eyes bore holes in the canvas. The deadline for the painting's delivery draws closer, and still he has not even picked up a brush. Finally, he rises up off the floor to approach the canvas. He picks up a huge brush and begins. Within a few hours the painting is done. . . . What Pollock was searching and waiting for was his vision. Once this had appeared, he needed only to render the vision on the canvas.
