Jon Jon krakauer's novel into the wild is based on the true story of Christopher Johnson Delaisse, a young man from a wealthy family on the east coast of the United States. He lost contact with his family after graduating from college in 1990. Looking forward to returning to the primitive life of nature, Christopher changed his name and surname, burned cash, gave up his car and most of his property, and then drifted in North America.

So this movie is based on real people.
