From the Wikipedia articles:
Into the Wild is a 1996 non-fiction book written by Jon Krakauer. It is an expansion of a 9,000-word article by Krakauer on Christopher McCandless titled "Death of an Innocent", which appeared in the January 1993 issue of Outside. The book was adapted to a film of the same name in 2007, directed by Sean Penn with Emile Hirsch starring as McCandless.
The book & film are based on the travels of Christopher McCandless across North America and his experiences in the Alaskan wilderness in the early 1990s.
