actor/director Tommy Lee Jones namechecks Donald Judd & Dan Flavin--

"I would often sit around the monitor while things were being set up and ask different people if they thought there was any emotion in geometry. And they would say, "What?" And I would say, "Do you have any feeling for triangles? Hexagons?" There's a geometry to the film that I find very pleasing. I think Judd's work is highly intellectual and deeply emotional. And of course the influence of Flavin is obvious in the lighting, but nowhere more so than in the scene at the clinic where the border patrolman gets cured of his snakebite."
