Duvall’s Lt. Kilgore, of Apocalypse Now, may have had one of the most tiresomely quoted lines in all of 1970s moviedom—the one about loving the smell of napalm in the morning—but his character has a gruff complexity that can’t be encapsulated with one line. Even his very carriage seems to harbor secrets: Kilgore is a hard-ass, a walking scowl, but even so, he’s a man with a past and a future we can only guess at. A Duvall performance never stopped at a movie’s end; we could somehow imagine these characters living beyond the frame, inhabiting lives we’d never by privy to.
