Man in the Wilderness is a 1971 American revisionist Western film about a scout for a group of mountain men who are traversing the Northwestern United States during the 1820s. The scout is mauled by a bear and left to die by his companions. He survives and recuperates sufficiently to track his former comrades, forcing a confrontation over his abandonment. The story is loosely based on the life of Hugh Glass. It stars Richard Harris as Zachary Bass and John Huston as Captain Henry.

A mountain man is an explorer who lives in the wilderness and makes his living from hunting and trapping. Mountain men were most common in the North American Rocky Mountains from about 1810 through to the 1880s. They were instrumental in opening up the various emigrant trails allowing Americans in the east to settle the new territories of the far west by organized wagon trains traveling over roads explored and in many cases, physically improved by the mountain men and the big fur companies, originally to serve the mule train-based inland fur trade.
