Apocalypse Now (Francis Ford Coppola, 1979)
Two soldiers are chatting (about meat, appropriately) when the jungle goes still. They know they’re being watched. They get their guns ready—and suddenly a tiger bursts from the greenery. For horror, it hardly compares to all the human violence in this movie. But it is, according to the hunter and writer Peter Hathaway Capstick, the most realistic depiction on film of what it’s like to be attacked by a big cat.
