In this Best Picture Oscar winner, directed by Joel and Ethan Coen, Llewelyn Moss (Josh Brolin) stumbles across a satchel containing $2 million in drug money. He takes the satchel and checks into a cheap motel, hiding it in a conveniently placed 20-in.-by-14-in. duct. At about 2 sq ft in area, the duct would be expected to pass perhaps a thousand cfm into the room, which, at about 200 sq ft in area, would have become a wind tunnel. As luck would have it, we are shown a map of the motel. With Moss’ room located midway in the building and the satchel having been pushed all of the way into the main duct, half of the units would have been without air. It is understandable nobody complained, what with Anton Chigurh (Javier Bardem), a psychopathic killer hired to recover the money, showing up with his captive bolt pistol, taking out three men set to ambush Moss; lack of ventilation was the least of their worries.
