A reader, catching up on his DVD watching, notes: “In the film ‘Apocalypse Now,’ there is a scene in which the man sent to

kill Colonel Kurtz (Marlon Brando), Cpt. Willard (Martin Sheen) informs the

commander of the boat on which he is being transported (not a Swift, but the

smaller PBR) of his ultimate destination. ‘The Chief’ looks at the map and

observes, ‘That’s Cambodia.’ Willard replies, ‘That’s classified.’”
