The Snows of Kilimanjaro (H. King, 1952)

The story centers on the memories of disillusioned writer Harry Street (Gregory Peck) who is on safari in Africa. He has a severely infected wound from a thorn prick, and lies outside his tent awaiting a slow death, though in the film it is pointed out he may have acquired the infection from leaping into a muddy river to rescue one of the safari’s porters from a hippo after he falls in the river. His female companion Helen (Susan Hayward) nurses Harry and hunts game for the larder.
